down pipes

[wrdmotorsport]

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.

Put me down for them

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.

Does WRD offer interest free credit?!

[wrdmotorsport]

yes at 0 rate credit , pay in one lump sum and have the goods delievred in 12 installments

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...

I have a normal stylie arrangement and it works well

I wouldnt worry about equal length personally.. but im no experto.

Haha

Didnt see that above post...

Just for info my downpipes were about £330 if i remember right... so @ £200ish its a bargain.

[wrdmotorsport]

thanks for the use of your pic

[Mikesone]

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.

[wrdmotorsport]

the test car will be on the rollers tues then after fitting
