3" Downpipe fitting!

[krisrg87]

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

The OP's car is an S3 mate...

I didnt have to undo my subframe btw, and for the quattro boys... 2 words- good luck! Lol. Its a pretty tight job as it is and doesnt need anymore parts restricting access

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 )

Evo in September, cough, cough

They are indeed a P.I.G

 

[<tuffty/>]

Urgh, nobody likes a challenge anymore!

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.

 

[Prawn]

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

muhahahahahaha.

I hate you. Imagine how far I wouldn't get without the good old Haldex! lol

 

[krisrg87]

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.
