    3" stainless steel cat back system

    I've been thinking about it for a while and finally decided to share the idea to see what people think abouti it.
    I've been making downpipes for few years and somehow there still is some interest. It would be good, if there was an option to supply full system, so all we need is cat back system. The hardest bit is, that apparently there are few different options depending on pfl, fl, Legnum, Galant. Put me straight if I'm wrong. Other thing is, that the best way to do it would be to build the exhaust on the actual car, but as we know, because of distance, spread of all of VR4 drivers all over UK, Europe and further it simply wouldn't be possible. The best option is to supply ready kit just like the downpipe, which could be a little bit tricky because location of tailpipe in a rear bumper is very crucial.
    Other unknown important aspects are price and what would people prefer: straight through pipe with back box, resonated pipe (how many resonators) with back box and other options.
    Another thing is, that I may be waisting my time, because there are already options out there which would be simply cheaper.
    Please share your thoughts on this subject.

    If you need a PFL Legnum to be able to create the system from then if you have access to a flatbed/trailer then you can take the purple one until you have a prototype made up. The only thing is that it is missing downpipes and a cat lol.

    Option there if you need it and have somewhere to store the Legnum.

    I'm interested, own a PFL Legnum VR4, but live in the Netherlands. And a drive to the West Midlands would be about 900Km's. That's a lot of Petrol, lol...

    So if you can line it out on another PFL and the Price is right, you'll atleast have one customer.

    The only difference I was aware of, was between Galant (saloon) and Legnum (estate) - length, saloon version being shorter.
    Ex: Galant VR4
    Running 268 HP ATW and 443 Nm torque at 0.9 bar
    Now: Lancer Evolution 8 FQ-300
    Running 325 HP ATW and 510 Nm torque at 1.6 bar

    So sounds like there is no difference between pfl and fl ether galant or legnum.
    Are back boxes and tail pipes the same for pfl and fl?
    As far as I know bumpers are different.

    AFAIK there's not a difference in between pfl fl galant or legnum. I put picture somewhere of one pfl legnum lay on top of fl galant, both are exactly the same.

    I believe the stock tail pipe was about 40mm longer on the estate, but that was it.

    Legnum and Galant were the same?
    Isn't Legnum longer than Galant, like others said above?

    I've posted this previously in another thread about size and weight comparison.

    'the Legnum is only 16cm longer than the Galant and about 70KG heavier, so really no difference between them.'
