My last one was noisy too. I just worry. I guess at the least when I get down to have it tuned maybe Justin will be able to tell my if something is off.

 

it could be a melted cat or broken cat and the pieces are rattling around in side the cat. tap it with a rubber mallet. i also had the heat shield above the muffler near the evap stuff rattle.

 

If the cats are gone it's not a big deal, I'm going to be putting longtubes on soon.

 

yeah my driver's side cat is busted and it makes noise similar to what you're talking about. tap the cat with a mallet like billy said and if it rattles, there's your problem. hopefully in the next couple of months i'll have my longtubes and i won't have to worry about it either.

 

Mine is on the driver's side too. Guess I should have said that earlier.

 

Yep, it's the DS cat.
