Tone,
To be clear, I wasn't suggesting throwing out the silencers if cutting down the pipes is the only way to go. I'm glad Mike chimed in on this, considering his experiences with overlong pipes. I have no such expereince, not because I've had mutliple sets of perfect pipes, but because I've only ever bought one new set, which worked after I removed the burr from the inside of the silencer.
