    Well all i can say is hopefuly i never have to do that again. Started at 5 at headed home at 12! Could def be done alot quicker next time round bout what **** of a job. Thanks to tuffty after searching some posts. I had to laugh though, after deciding the only answer was to destroy the flexi to split the pipe in two, i cam across my air chisel, then read thats exactly what tuffty had done haha.

    I had a bit of a time trying to find the best way to do it, so heres a quick how to from my tired mind.

    o/s whell of and you will be able to see the 3 nuts to the turbo, and remove the drive shaft to allow access.
    I got 2 from the arch and 1 from above.
    Grind of the bolts connecting the DP to the Cat and seperate.
    Sounds brutal but hack the flexi on the DP until you have 2 DPs and pull the bottom out the bottom and the top out the arch.
    Loosen the sub frame and dogbone to allow movement and the 3 bolts for the prop shaft nd move to one side.
    This the allows you to put the new DP through the bottom and into place.
    Then its pretty much a reverse procedure.

    If i have forgotten anything feel free to add. Apart from that, im very pleased with it, can really hear the turbo now

    Urgh, nobody likes a challenge anymore! I remember the days of putting v6's in MK2 golfs,

    KO9 lumps in Mk1 civics.

    Skyline engines in Mustangs.....

    In all fairness thought, they do "make" a proper de-cat for the S3. Us poor TQS who couldnt afford the S3 ( apprantly ) :blownose:

    Evo in September, cough, cough

    They are indeed a P.I.G

    The S3 is the tricky one... K03 cars are much easier including the TQS A3... :)

    If you think getting an OEM downpipe out is hard, try fitting one. Not a fun job.

    Dead easy on a ko4 FWD A3 boys :) infact, it's all easy!

    Ko3/s FWD downpipes are a walk in the park, ko4 wasn't much harder.

    Who needs a haldex anyway :racer:

    muhahahahahaha.

    Thanks for the replys. Yeah the haldex made it difficult to say the least but i still wouldn't have it any other way!

    Welly if someone asked me to fit a oem dp i would kindly tell them where to put it.

    Superkarl, i found there wasnt any other way then loosening the subframe, it was very easy though, just 4 bolts. It dosnt move that much but its enough along with moving the prop shaft, Good luck.
