Looking at a new exhaust for a 77 750 - the original is shot. OEM is unfortunately out to price. I've got a MAC 4-1 on a 550, and they're OK but I'm also looking at the Carpy exhaust as an upgrade. Anyone have experience with these? They obviously are well built compared to the MAC, but a) are they significantly louder and b) will they change the back pressure enough to require a jet change, and c) do they interfere with the rear pegs?
Since I'm familiar with the MAC, does someone have experience with both?
