Hey guys. its been a while since i've been on but i'm wondering whats the difference in exhaust pipe back pressure between the indy 440 and 500 both liquid cooled.
Do to circumstances im boring the sled out to a 500.
I've already got the head on order and the jets well be in soon just wondering if im going to have to change the exhaust to a 500 because of back pressure.
thanks for the help
