It's a cool sound with OEM exhaust and probably a slip-on exhaust but it's a different story once you go to full exhaust.
I had an RPI x pipe with gintani race exhaust (no cats) and it sounded incredible. Really sounded like a nascar cold and full throttle onramps the car sounded unreal. But I went back to the stock x pipe and a Supersprint rear section for a little change in pace.
