Not much with high flow cats but stock headers & cats to aftermarket headers with offroad h or x night and day!!!I want headers but I already have a corsa sport and I don't want it twice as loud as it is now. I may have to find me a stock resonator. Is there much sound difference between catted and non?
Any video clips?After staring at them in my garage for months knowing I won't have a free weekend til probably winter, I went ahead and paid to have them installed. The guy who owns the shop was a long time Ford tech who I used to work with. He said they were the nicest headers he's ever installed. Great fitment and great quality. Definitely love what it did for the sound. I have a h-pipe and stock mufflers. Probably start looking at mufflers in the spring. I have a Lund tune, may try a datalog and see what he says. Thanks RDP Store for the great deal on the headers. Sidenote, I did use new Ford manifold gaskets.
It won't be twice as loud. Sports should be fine w/headers.I want headers but I already have a corsa sport and I don't want it twice as loud as it is now. I may have to find me a stock resonator. Is there much sound difference between catted and non?
