has anyone put a test pipe on ur turbo z31? i saw a 2.5 inch test pipe on ebay for 30$ with everything u need to install it. i kno its illegal so no need to remind me. can u get any kind of performace gain from a test pipe? would i make it any louder?
there is nothing wrong with my cat(that i kno of). i jus want it to be a little louder and a little bit of performance. is it worth 30$ for the sound and performance? will it make it sound good or like a honda or something?
