When you have the bucks move up to the RB SP setup which is dual pipes to the rear
into a single RB muffler. I had a similiar system to yours before that and it was a real
eye opener when I made the change.
At any rate, a header with a good flowing exhaust makes big improvement.
Why do the cat? Legal issue in your state?
