Default Re: Expansion chamber header pipe angle question

When I had the 3, 45 degree copper 1 inch pipe connectors it had more power and sounded like a sick dirt bike . You could hear the expansion chamber And it was on the power band the whole time. It felt smoother when WOT and topped out. Now it shakes and vibrates when it's WOT topped out and slower now!!
I don't know what to make of it, it was way better with the copper than the steel pipe I welded.
