So I've got an aftermarket H pipe that i catted with magnaflow high flow cats a couple years ago. Anyways, the car seems to "die out" under load. At first i thought it was a fuel issue but my wideband is showing normal AFR. No bucking so it's not a spark issue. I figured plugged exhaust was the next alternative.
It's there a way to check for plugged cats? Even if i pull the pipe off I'll only see the front screen of the cat anyways correct?
