Default RE: Cutting the y-pipe for H-pipe duals. Affected Backpressure?

well most race engines are carburated, but thats besides the point[8D]


the 4cyl mustang after 1985 was efi, and that car needed all the backpressure it could get


What the hell does that have to do with back pressure? It's not the induction system that's affected it's the cylinders and they need a certain amount of scavenging to make power and if you have too much free flow you lose low end power.
