think ive decided to go with the FI catback exhaust (although i still like the HKS and Stillen), i need to decide if should i go with traditional with the 4" tips or round with the 4.5" ones, im not looking for anything too aggressive sounding so im curious if those with the round pipes are much louder, any input/advice is appreciated.

 

I'm not sure the tips make a difference in the noise look wise i think its a matter of what you'd prefer

 

not the tips but the muffler cans, the traditional has a larger oval shaped can will the round has a smaller round can, ive heard the round can be louder and more aggressive sounding, im just curious how much

 

your getting the original FI exhaust? or the carbon?

 

it would be the non CF one but they offer two types of mufflers, the traditional and round
