Ok, im not sure if it is even worth the money or the hassle, im trying to keep the car as quiet as possible, and plan to keep the stock exahaust.....


a)If I install a megan header and S pipe, how loud will it make the car?
b)It eliminates the cat, but thier is a second cat no?
c)What kind of gains if any without a custom exhaust can I achive with just the install of the megan header and S pipe?
