I'm replacing the stock, double wall, chrome plated, heavy ass exhaust on my nighthawk with a custom (home made) ss 1.25" system and Vw 1.5" chrome flared tips.
The id of the the stock piping is .900" and the id of the ss piping is 1.100". That is actually 50% larger than stock. With all this extra flow I figure some sort of tuning is in order.
This is where I need help. Is baffling an exact science? Will an h-pipe help? What about an h-pipe with a butterfly valve?
