<< This has never been my observation. The only time that lower backpressure
hurts a motor is when the intake system cannot compensate and runs too
lean, or when the engine EGR is designed with an extreme amount of
backpressure. Both of these situations could be adjusted for.
However running larger pipes than neccessary does lower the available
scavenging, if any could be done in the first place. >>
What about with Catalytic converters ? To my thiunking the Cat has got to be
the bottle neck ? So how can bigger pipes past it hurt performance ??
