i've noticed that it is almost impossible to get a 3" exuast for the TT. I've decided to have a local muffler shop here where i live make me a downpipe and midpipe (from converter to muffler) with 3" piping. I'm thinking of using an Apex'i N1 turbo muffler and a high flow 3" cat. does anybody have any experience with a 3" exuast with a tt? also who would the best company for a chip be to go through? reason i ask is that my V-6 biturbo plans have been put on hold until i can come up with a wrecked S4 for the motor, tranny, rear end, and harness. Thanks for any help in advance.
