Howdy folks - looking for a bit of feedback as I continue to troubleshoot.
AWE suggested that it may be the mufflers themselves - a loose baffle. Not unheard of it appears in searching here on both vanilla variety C2S and PSE mufflers. My '05 C2S has more miles than most, 56,000.
I tested the mufflers via the good shake method and hear nothing loose. Before removing them, I tried to replicate the decel rattle that others have posted on loose baffles and didn't hear anything. It's possible that it's a baffle that's loose, but not loose enough to rattle with the stock cats in place.
So, right now, I have two mufflers and two cats that do not rattle when off the car. Short of x-raying them, I'm unsure of how to diagnose from this point forward. I have not yet reassembled with new sleeves (arriving tomorrow) - but about the only thing I can think of to eliminate one or the other is to replace the OEM mufflers with replacements. Before I waste AWE's time, I figure I'll replace the mufflers to at least rule that out before returning the cats.
Does anyone have a pair of C2S cans sitting around gathering dust? I figure while everything is off the car, I'd like to just try that before using (wasting) the new sleeves and clamps on the original cans. If it still rattles with new clamps and new(er) mufflers, I'll feel farily certain about returning the cats to AWE for diagnosis and replacement if neccesary.
Anyhow, please PM me if you happen to have a set of mufflers lying around that I can purchase from you.
