boost69 Donating Members 737 Member For: 19y 11m 23d Posted 25/02/15 12:18 AM Share Posted 25/02/15 12:18 AM Guys,Does anyone know any definitive way you can test your cat to see if it's flowing like it should?Could symptoms of the increased back pressure on a stock BF XR6T be;4 psi peak boost pressure? (im assuming this is 1 or 2 psi off the stock figure)Occasional pinging?These are the symptoms I have experienced, and I'm thinking it could be an exhaust restriction problem...Have looked at boost and manifold leaks and apparently AFRs are within what's normal...How can I rule out a cat converter problem?

You can then easily tell whether it is your problem or not by looking at it.
