I had the TRD exhaust installed on my 99 4Runner when I bought it. I had noticed some rattling lately and found that one of the hangers on the muffler had popped of. I will have to get that welded back on. While I was under the truck, I noticed that where it bolts to the cat, that it was pretty loose from rattling. I was wondering, is there supposed to be a crush gasket between the Cat and the muffler pipe? If so, does anyone know the part number and if it a special part when using the TRD cat back exhaust?

Thanks a TON in advance! <img src="/forums/images/graemlins/smile.gif" alt="" />

Yep on the gasket.

Dunno on the p/n

I think it's a stock doughnut gasket. I'll try to dig through my pile of documentation to see if I can locate a p/n.

cool, thanks a bunch Wyatt.

I figured it was a regular crush type gasket, just didn't know if there was a 'special' one for use with the TRD cat back
