How long does a cat last for?

If you do an exhaust upgrade then i would replace it anyway, but if your emissions and performance havent been hampered, then it should still be good, but it wouldnt hurt to replace it either. Only way to tell if it iis bad is if you take it to get emissions tests doen and they are out of spec, or if it is clogged you will feel a definent power loss.
 
That depends on a lot of variables some last more than others but if you have 193k I would replace it regardless.
 
Good! I was thinking the same thing, just wanted some other thoughts...thanks guys!
 
Ya, I'm 185K with the original CAT and I passed the sniff test with it.

Course, if you think you're losing power and don't have the fundage for a new CAT, you could drill an 1/8" hole at the head of the CAT intake to relieve backup pressure-makes a big difference when you pop that hole in.
 
Thanks again!

Yep, Connecticut has emission testing and they check for them at most stations. Isnt really a big deal got to much power anyways....LOL
