My buddyand i are working on his teg, we took the exhaust off to see if there is anything in the cat, while reassembling it there seems to be a siginificant amount of sand or somthing in the resonator.
it looks like black flakes of crap. nothing spectacular
but could it be KILLING his performance of is it normal?

 

Hmm, blown out catalytic convertor.................

 

his cat appeared to be fine tho, and the crap in the resonator wont come out, at all.

ill pass that along tho.
