exhaust systems

[Russ]

many times over the yrs, i hear that "back pressure" is important in the ideal engine performance.........OK......now many of us fit auto engines into aero use and generally things go along just dandy.

 

So...........are our auto/aero installations with next to zero design re exhaust performance, but targeting "noise" reduction as paramount, disproving the "back pressure" theory.

 

Am seriously considering canning my current HEAVY exhaust and going to a single canister each side of the soob.
