OK material will be ordered on Monday and tooling will be in place next week.

1st prototype and jig will be made next weekend.

so can i have a show of hands for people who want 1 they are going to be in the ballpark of £200, 304 st/steel 2.5" from turbos to joint and then in to 3" tothe cat.

Just a little thought;

Would it make any difference if the joint was 3" and the increase was just after each turbo?

Just wondering?

OK out of the turbo is 2 1/4" so if you go to 3" you are increasing for no reason then you have got 2x 2.5" tube =5" tube cubic capacity going in to 3" so again no need to go to 3".

we are going to 2.5" from turbo because 2.5" is more readily available.

Nice one..

I have no idea about exhaust design.. should be good.

PM inbound for another WRD idea..

I would make the pipe from each turbo increase in size up to 3" just before the join though, maybe 20-30mm before the join, just to make sure there is no restriction where they join up.

On a more serious note - Are you going with the more traditional straights into Y-pipe, or a more fancy equal length design?

This is the equal length one...

Interested in what you think this offers in terms of performance, effects on boost, Fuel cut etc.

Thanks

Axeboy

I have these fitted.

Performance did increase, but difficult to estimate a gain with a rolling road. Pickup is improved and the car revs more freely. Estimate maybe 20hp, but its just a guess.

My car holds boost to the red line since fitting, I expect this to be the downpipes but I did some other minor mods at the same time.

The noise is heavily improved, I do like the noise, very gruff and raspy, but not loud.

Thumbs up from me.


If I didnt already have it, my name would be down for it.

OK out of the turbo is 2 1/4" so if you go to 3" you are increasing for no reason then you have got 2x 2.5" tube =5" tube cubic capacity going in to 3" so again no need to go to 3".

we are going to 2.5" from turbo because 2.5" is more readily available.

Area of a circle is ~3.14*r squared

2.5" pipe - 3.14 * (1.25*1.25) = 4.9"squared
3.0" pipe - 3.14 * (1.5*1.5) = 7.0" squared
3.5" Pipe - 3.14 * (1.75*1.75) = 9.6" squared
4.0" Pipe - 3.14 * (2*2) = 12.56" squared
5.0" Pipe - 3.14 * (2.5*2.5) = 19.6" squared

So as you can see, as pipe diameter increases by a factor of 2, the actual flow rate increases by a factor of 4

from that you can see that two 2.5" pipes flow a little more than one 3" pipe. However, to match the flow rate of two 2.5" pipes, you only need a 3.5" pipe.

It is important to remember this when dealing with pipe work.

yes and from your own calculations Kenneth you can also see that 2 X 2.5"pipes comes to 9.8" squared that is almost 1/2 of 3" again,

IE 7.0" divide by 2 = 3.5 which is almost the difference between 9.8 and 7.

so in conclusion it will be the 3" pipe that is going to be the restriction.


how big do you need to go./help

also the turbos are 2 1/4" outlet so that makes the tubo outlet 3.14*(1.125*1.125)=3.97"square that makes the 2.5" pipe over 1" squared bigger.

OK so does this put it to bed we are going to use 2.5" pipe

At no point did I say that the 3" pipe was NOT going to be the restriction.
I thought my calculations made it very clear that indeed even with 2.5" the down pipes would outflow a 3" system from the collector on.

There were 2 main reasons for my post.

First off is this statement

...then you have got 2x 2.5" tube =5" tube cubic capacity...
This statement is incorrect. While you may or may not have said it as a quick generalisation, I feel it is important to give the correct information, even if only so that people are not mislead and possibly later embarrassed, when the repeat what they heard from someone who they believe knows what they are talking about.

The second is that you only need to go 1/2 an inch bigger in diameter to get almost the same flow as two 2.5" tubes. I haven't been under the car in a while, so I am unsure if a 3.5" exhaust would fit. If it does, it may be worth a look.

wrdmotorsport
15-01-2007, 04:01 AM
OK......kenneth i totally agree i did state that incorrectly i didn't sit down and calculate the square inch of two 2.5" pipes. but as you have also pointed out there is no need to go to 3" as other people were saying.

As for 3.5" i don't know off anybody with 3.5" zorst so i think it will be pointless to go for 3"down pipes.

PS sorry if my last post came across badly, im just trying to point out that there is no need to go to 3",as you are as well kenneth

When I spoke to Longlife Exhausts about a custom exhaust, they seemed to think that a 3inch pipe on a std car would actually loose power. However, if I was planning on going for 320+ BHP then a 3 inch sytem would be justified. Don't know what these figure were based on, but as they stood to make less money from the 2.5inch system, I assume they were genuine in their advice.

Prices I was quoted were:
2.5inch cat back: £449.00
3inch cat back: £780.00
High flow cat: £169 to £299 depending on which model I went for
Downpipes: £399.00

Which again makes WRD's pipes a bloody bargain.

My Blitz system is a 3 inch cat back job. With the cat on - it feels a little more lively than standard.

Decatted, it really comes into it's own and the power hike is impressive beyond 4000 rpm (even against a decatted standard system).

No worries mate. Bit of a mix up is all. I am looking at doing some exhaust work myself, after looking at the figures I am sorely tempted to try for 3.5" collector back... be interesting to see how it works out.

Thinking more, I don't know if there would be enough room to bolt 3" downpipes to the turbos... not a great deal of room on those flanges...

Nutter_John
15-01-2007, 09:58 PM
Think you would struggle to get a 3" connected directly to the turbos as the bolts for the flanges are just over 3"'s apart , only option would be to use 2.5" then flare it out to 3" once clear of the stud's

well, there is a small possibility that you could loose a marginal amount of torque at low RPM, but this is more than offset by the increased turbo response.

With a 3" exhaust and 2.5" downpipes I was able to get over 15psi boost at 3000 RPM in 3rd gear. I think it was around 12psi at 2500RPM
edit - btw... this was found on a later run with a MBC installed and set at about 15.2PSI

The guy at the dyno (Robin) was was amazed at it, and came out and had a chat with me. Apparently the best boost response he has seen.

I have attached my dyno sheet. The Blue line suffers electrical misfire at high RPM, so thats a bit stink as there was no indication of max power.
However the Red line is with the 3" exhaust installed (Blue is standard with de-cat)
They put the boost reference in wrong for the Red run though, so the boost line is pretty useless... probably peaks at about 12PSI though.

To cut a long story short, the graphs clearly show that from 2000RPM up, the 3" exhaust gives better performance.

Very interested in these ... can you put me down as a 'provisional' for now until I've cleared it with the management /pan

Just out on interest ... can someone tell me what the difference is in terms of the bore compared with the standard downpipes and any idea what the bore/connection on the standard cat is ?

wrdmotorsport
13-03-2007, 11:52 AM
The tube from each turbo is 2.5" stainless which then joins into a 3" pipe with flexi and then continues as 3" until it hits the cat point .

I think the standard cat is around 2 1/4" so a nice 3" de-cat pipe will be just the ticket for you wayne

Now we have had a lot of PM's around when these are going to be ready , well as you all probably know we moved into a bigger garage a few months ago , have installed a four post ramp . Unfortunatly we have been so busy with servicing lot's of peoples cars we have not had chance to get on with these as quick as we wanted . But heres the good news , we have not taken any bookings for this weekend and will be spending the entire weekend getting as many made as we can .

look out for an update some time Monday as hopefully we will be relasing the first batch for sale .

Thanks for all you support and patience it is much appreciated

The tube from each turbo is 2.5" stainless which then joins into a 3" pipe with flexi and then continues as 3" until it hits the cat point .


Cool.

Will that be okay for people with standard size cats though - will it offer up okay?

Do you have a 3" inlet/outlet Sports Cat on your list of plans at all?

Hi Keiran , yep the flange that connects to the Cat is the smae size just with a bigger internal bore .

We have 3 test cars to try the design out on this weekend to ensure that it fits all types of exhaust and cat combinations .

And as for a sports cat the simple anser is yes , but before we release anything we want to research a little more as we wnat to make sure that the version we supply will flow nice and freely and also pass emission tests . So watch this space

I think the standard cat is around 2 1/4" so a nice 3" de-cat pipe will be just the ticket for you wayne

All in good time /Devil5

So, if I fitted the downpipes to my current system, I would have:

downpipes to cat 3"
cat itself 2 1/4"
cat back aftermarket exhaust 2 1/2"

is that a good idea ?

I've always thought going from smaller to bigger bore over the length of the exhaust system was ok but is it ok to go bigger to smaller ? i.e. even if I fitted a 3" decat I would still be going 3" into 2 1/2" is that ok ? :thinking:

Having just had the new system fitted I don't really want to change it to a 3" in the new future ...

Nutter_John
13-03-2007, 02:53 PM
Don't think you would have to change your exhaust as mine is only a 2.5 until it splits and I will be using a 3" de-cat ( sorry sports cat ;) )

If you leave the cat in place on your car Wayne then you will have quite a bottle neck as the gases try and rush into a small space , probably best to shove a de-cat / sports cat on that is at least 2.5" to giev you the best flow

Flame me if i'm wrong /pan But it doesn't matter which way round the cat go's.. It's the same thru the Cat both ways.. The only thing that stops us installing it the other way round is the offset phlanges..

Nutter_John
15-03-2007, 09:42 AM
Glen you are correct the cat is bi-directional and we have infact had a car in the workshop that we looked at for about ten minutes because we could not work out what looked different , then it clicked as the cat was the wrong way round

I will explain the best I can when you change the diameter of the pipe from a larger bore to a smaller size the amount of gases going through the pipe will in effect have to force there way thru , this can creat a small amount of back pressure which will mean that the gases will not be exiting at a free flowing rate . I would not think that the cat's life would be not reduced by this as the same amount of heat is still in the cat as before .

I will try and find a fuild dymanics package i used years ago anf see if i can plot a graph to show this ( but it's been 14 years plus since i looked at CFD)

White Lightning
15-03-2007, 11:41 AM
Glenn - I didn't mean putting the cat on the wrong way around ... what I meant was if I got the WRD downpipes I would have this setup:

With current / standard cat:

Engine > Downpipes 3" > Cat 2 1/4" > Longlife Exhaust System 2 1/2"

With 2 1/2" decat / sports cat:

Engine > Downpipes 3" > Cat 2 1/2" > Longlife Exhaust System 2 1/2"

With 3" decat / sports cat:

Engine > Downpipes 3" > Cat 3" > Longlife Exhaust System 2 1/2"

Either way it seems to me that there will be a bottle neck at one end of the cat. Engine end with the standard cat or 2 1/2" sports cat. Rear of car end with 3" sports cat. If you see what I mean ...

No Mate you don't need to be a member, however I think the boys are working it on a "who put their name down first" basis. They are doing them on demand so if you are interested they can do it for you.

As the std downpipes are quite restrictive, I suspect you'd see a decent gain with these - backpressure must be lower with the wider pipes...

Changes in diameter are best avoided, but if you have to, the further downstream they are, the better. It would be better to continue with 3inch, but even with 2.5 cat and on, the wrd downpipes have got to give better flow than the std rubbish,

Good. Good. Well I've still got the standard cat at the moment which I believe is 2 1/4 ". I would like to replace it with a sports cat at some point (in fact it may need changing before the MOT this year as I only just scrapped through the emissions last year). So it sounds like I would be best off going with a 3" sports cat to match the downpipes so that the reduction in diameter is further downstream.

Perhaps it will be worth me waiting on for the WRD sports cat ... :scholar:

where are these pic's
i am interested to see the result even if i haven't got the fund to buy one. although it would be good investment as my first flex section of my exhaust has been warn away and the ribbed bit inside is ground down enough to let a little exhaust gas out at idol. probably lots more get out at high revs. I realy need to plug that leak sharpish.

one question, am i right in thinking the front section of standard exhaust from the bottom of the turbo to the front of the cat is one piece.

if any of you get one of these new down pipes do you want to sell the original.

But yes, I've seen a prototype. Interestingly - and to my mind a good thing - Richy's worked on his own design and the net result is a system that looks very, VERY similar to the YR-Advance downpipes that one can get in Japan for the legnum. These get very positive reviews from Japanese owners on www.carview.co.jp (yes, I am a regular there...../pan)

What I will say is that I do have the set on my car and have had them on for about a week now , no RR results but they do feel better so much so that I have had to turn down my boost as they flow a lot quicker and i was hitting fuel cut due to the onset of boost quicker than before

If he doesn't already, I would suggest going with a 600x300x79 intercooler and doing the maf mod.

also make sure it IS fuel cut and not misfire... when it was doing it on my car It pretty much felt the same, it wasn't till they put it on the dyno that it was diagnosed as misfire.

Should I come down and see you on an individual basis then folks. This isn't a peformance upgrade any more, I've got a hole in my stock ones....dear liza!

Not even got an EBC so I don't think fuel cut is going to be a problem. I was always under the impression that when downpipes/decat/exhaust were fitted that the turbos would run that more effeciently, boost could be knocked down.

Just got from under the car and the first flexible part of the downpipe is not good anymore. So VERY interested in more info on the WRD downpipe. Updates/pictures & prices (shipping to the netherlands) please!

Looks like a great setup so far, I would be interested in the future, but maybe not in the first batch - need to get the Leggy to stop better before I make it go better!

have you made the down pipe equal length from turbo's to keep them balanced. to keep boost stable.

Well, the prototype pics earlier in this thread suggest not. However, given that they're a bigger bore, the extra capacity for gasflow probably means it won't result in a huge imbalance.... I think?

Correct K , Also the amount of room under the car to use equal lenght would make it even more difficult than it already is .

On a side not I'm not sure that equal lenghts make a difference on turbo cars as you don't need to balance the flow to generate back pressure like you do on a N/A car .

yeah the tiny little TD03 exhaust housings are going to limit the flow by quite a lot, so the length of the pipes isn't super important. In an ideal world they would still be equal, but it isn't strictly necessary.

Please keep us updated to how you are getting on.

I've been running around with a rather large rumble from up front for the past 3 months in anticipation. Don't want to go the standard replacement route, as I don't see the point if these are in the pipe line.

Any idea on an ETA?

Thanks

Tim

okay... now WRD is no longer an option for us (me) does anyone know where I can find AND buy a proper downpipe? The Japanese sites mentioned in this and other topics show nice examples of downpipes, but I can't find one where I can actually order one! Any english speaking webshop would be very welcome!

Thanx.

I've decided to make my own full system. 2 1/2" from turbo's going into 2 into 1 joint from then on 3" no center boxes straight out to rear silencer. all in stainless. Just need to wire garage for tig welder and then i will be ready to weld.

Well, Your options as I see it are as follows...

1. Custom - Either DIY or Powerflow, etc. etc.

2. Pro-Shop IIda downpipes - http://www.ps-iida.co.jp/galant/galant.html

3. YR-Advance - http://www.yr-advance.com/parts/p026.htm

Options 2&3 can be got by contacting www.rhdjapan.com - they will have to special order them, but their service is good and the price is normally quite reasonable. www.takakaira.com may also be able to assist, but again it would be a special order case.

Diy all the way. Sick of paying money to people who can't be arsed doing a decent job. Had one custom exhaust made and fitted in last year. load of rubbish the welded joints leaked, it hit against the drive shaft and it came with life time guarentee. but they went bust so had to pay someone else to alter and repair. In the end the job looks the sh*ts.

so where possible i am planning to do most mods/repairs myself.

OK, so the question now is should we get equal length or just a re-make of the Mitsubishi ones?

The only equal length ones I know of are the Pros Engineering ones (different to the Pro-Shop IIda pipes). Most aftemarket ones are either 'F' or 'Y' pipe designs. They'll still be better than the Mitsutwitty ones, though from what I've read on Carview, the F-pipes do sacrifice a little low end grunt but have a much better top end.
