the entire component of having a extra effective exhaust is to launch back stress. hondas are made for horsepower and not torque so merely purchase a cat back exhaust with tremendous diameter exhaust piping.
I'll tell you right now. If you go and buy that POS exhaust, its going to rust the **** off and real quick like too. Its also going to sound and look like crap. Don't expect it to last long. Invest in a better product and save your time and money in the end. Check out Thermal, HKS, Injen and companies like that. Anyways, if it doesn't and you put a new exhaust on there that doesn't have a cat either. Just have an exhaust shop install one for you when they put the exhaust on.
