Yeah, essentially they are a two-stroke engine and the amount of
continued combustion that occured in the exhaust pipes is unreal. It's
actually important to have a little bit of back-pressure with those
engines if you want any torque. If all you are after is horsepower,
then open those pipes wide open. But an open and free exhaust knocks
out the entire bottom end of the power range. When a lost the exhaust
behind the second cat, I also lost about 1500 RPM worth of power
range, but gained 10-15 hp on the top end.

Yup, those engines are pretty much the equivalent to a huge
displacement two-stroke. Sound and fury.
