Could a bad exhaust cause engine problems like this...

Could a bad exhaust system(leaking, busted up and rusted pipes, manifold leaks) cause problems like stumbling and backfiring?

Thanks,

Matt

i have a tad of backfiring after i let off the gas sometimes and i am pretty sure my straight pipes where the cats use to be leak alittle, maybe even the headers alittle loose.

That might cause a popping sound, but not a real backfire (actually, its afterfire if its in the exhaust) and shouldn't cause a stumble.

Those sound ALOT more like fuel delivery problems than exhaust problems.
