hello, is my first post here. i'm looking for a good expansion chamber exhaust to put on my gt7 kit. Was gonna get the basic banana pipe for $40 but have found on several forums that people cut them open only to find literally just has a pipe hiding inside. so am here looking for some options on a real expansion chamber exhaust that will add some perf? thanks in advance.

If you want a chamber that is pre built look at the vendors on the sides of this forum, several sell them. Most require some work to make them fit.

Hey there,,I got a banana pipe on a BBR stage 4 engine kit...and as it came it was much better then a stk pipe...but after taking the Dremel and opened up the exhaust hole on the banana pipe..made a big difference imo...Lil bit loud,but peppy'..
