Backpressure test?
Has anyone here actually had a backpressure test done to check for a clogged up cat? Just wondering about how much it cost? None of the parts stores around here said that have a backpressure tester... I have really been wondering if my cat is clogging up but not sure how to test if it is.

Disconnect exhaust from engine
blow air into tailpipe from any source of compressed air
if it comes through, the cat is not clogged.
Catalytic converters are extremely reliable. What makes you think yours might be clogged?
