hectic_1 do u know wat brand u want to go for? cuz i wouldn't get one of those ebay knock exhaust cuz idk if it will hurt the car. i would get a reputable manf like line7 said.
But im still gonna stick with my tanabe either medallion or concept g. The price for the concept g is looking good for me. Ppl told me to go with greddy but i want sumthing that is not loud but at the same time i will notice sum power gain. but my #1 priority is not a loud fart can and a nice sound. and i dont want the hassle of slapping on a silencer.
