ok guys today i took the car out and floored it little bit it was fun. but i have question. the only reason im gettin this stromung exhaust is for louder sound and increase performance. i looked under the car and i see that new system will be hooked behind the cat and te diameter of the exhaust seems to be big enough and i was thinkin that the new exhaust system wouldnt give me hp. can u guys tell me the results after putting in the stromung exhaust. all i care about is performance i dotn care much about the sound. the stock pipe and muffler seems to be pretty big. can u guys clear this out for me plz
