Re: how much HP avg exhaust give single and dual????????
I am responding to both of your threads. Single or dual, you can make them loud or quiet. Does not matter. And more power single or dual? Again does not matter. It all will depend on what kind of system you put together. You can have a loud exhaust that will simply steel power. Loud does not = HP. A free flowing exhaust may free up some hp, but it not going to make you more. Unless you are working with scavanging and cam overlap. But I don't think you are ready for that.
Re: how much HP avg exhaust give single and dual????????
According to the specs the websites give, deleting the cat frees up 5-7hp, and the downpipe frees up 8-12hp. I cant say that I felt a 20 hp increase or not, but I did notice that it reved up quicker, pulled a little harder to redline (Or for me, 5500rpm ), and lost some low end grunt. But you gotta expect that when you take away backpressure. Theres a ton of threads on exhausts, use the search function.
