I'm having a technical issue. I have the banks monster exhaust and CAI installed on my truck 2 weeks ago. The exhaust makes a strange sound when i'm going about 40mph and about 1100 rpm. So im barely on the gas. It makes a pinging kind of sound. Almost like the engine is lugging and should down shift. The noise is even more dramatic if im going up a slight incline. It sounds like its coming from the exhaust somewhere and I dident hear it at all with the stock exhaust. Got any suggestions?
Sounds like it could be a loose baffle in the muffler. PM me your contact information and best time to call you, and I'll have someone in tech support give you a call.
