Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Removing the resonator

I nevre had any base dyno numbers for my car, but assuming these cars have exactly 200crank hp stock, my dyno numbers give me a *peak* gain of 8.xx (can't rememberthe decimal) HP. That is with a KKM and removed resonator. The stock res is a bottleneck in the SVT exhaust. Dron e isn't annoying at all...you can't even notice when you're on the highway, the rasp however is always there.
