Ok i have a 96 tsi awd.. and im wanted to get exhuast, Right now i only have 300 bucks as of right now. So i was thinking a 2.5" Downpipe and 2.5" test pipe and bolt it up to the stock cat back. Will that work? Also iv heard that it will not do much for performace but... oh well. If i go to the track i can just unbolt my stock cat back and run. Then i was planning on getting cat back in the spring. So basicly my question is.. should i do the downpipe/test pipe. Or save up a little more and get the cat back and test pipe now? Also will the 2.5" test pipe bolt to the stock cat back? Thanks for any help.
