Do I have a blown catalytic converter? Passenger side cat rattles like crazy while driving and at idle. I checked the catback and y-pipe to make sure everything is tight and it is. This sucks, I got this y-pipe new from Kook's along with my headers a few years ago. Oh well, what should my next move be? I'm getting sick of this y-pipe junk anyway. Maybe I should finally go with true duals? If I go that route there will be a Corsa up for sale soon.

I put a used TSP catted y on my SS. few weeks later car felt like a dog and had a weird noise coming from exhaust. had car in garage ,gave it a few revs and could hear a slight rattle in the exhaust. took it all down and both cats were GONE. all clogged up at the merge just past the rearend. doesnt sound too bad going thru the GMMG and no cats.
