    Do you think this option take sup too much room? I would ahve though it better to keep it as compact as reasonable without affecting performance. Then, when you stick in a big turbo, you only have to swap a flange and you will still have room for an airfilter.

      That's why I said space might be a issue. That was my plan, to just swap flanges at a later date. It's just an idea at the moment. You know your ****, so i'll take your advice seriously.

        Cheers for all the replies guys, im only planning on doing this once on this car si want to do it right first time. Would i be better off going for a 3.5" turbo back exhaust than one with a seperate wastegate. Im not going to be going for mega power, basically rs2 spec with 7a cams and larger intercooler and injectors.
        Thanks again

          Like Lee said, the S2 doesn't really have room for a 3.5" exhaust by the subframe....the UrS4 can clear that...so which car do you have?

            When I do my exhaust again I will get a complete 3.5" (might have to be oval to clear the subframe) and have a seperate wastgate pipe as well - But then I will be aiming for over 600bhp

            Just now I have a 3" downpipe, 1.5" wastgate pipe, but my exhaust reduces to 2.5" halfway along the car. It is good for 450bhp but not any more.

                When it looses traction in 4th or it feels too much of a handful - that will be enough.

                  Why worry about the rear subframe - just do a side exit. AFAIK its street legal as long as it exits behind the cars halfway line...

                    It is the front subframe - between that and the gearbox - it gets tight to fit a bigger downpipe down the gap.
