My exhaust is making a very very loud nise. It sounds like an old Nova SR with one of those tailpipes you could get your head up. I thought it might have a blow but I can't see anything and all the joints are sound. I also did the thing with the hand covering the tailpipe and it pressures up just fine.

A mate said it could be the baffles. I was just wondering if anyone has experienced this problem, and if so, is it more likely to be a fault in the rear silencer or what looks like the resonator near the cat?

Thanks folks.

Howdy

Mine did the same thing- see this thread and see if it helps at all
