View Full Version : Couple of 1.8T exhaust questions

12-15-2005, 04:59 AM
I am about to go the custom route for my exhaust setup because no one makes a 3" TBE (and I will be going APR SIII+), so I have some concerns...

1) If I do a 3" Labree testpipe + custom piping to a muffler, will that test pipe fit the GT-series turbo that APR S3+ comes with?

2) If the testpipe does not fit the GT-series turbo (or there is no adapter to make it from K03 -> GT28RS) should I just do a downpipe-back 3" setup for now, and complete it once I get my BT?

To my understanding, our exhausts are Turbo -> Cat -> Downpipe -> Piping to muffler.

Most catback setups already include a downpipe, just are without a cat/HFC. Argh.

Could I get away with just doing an APR catback? That way, cat is stock + piping all the way down from down pipe is 2.5"...
