Hey, guys For a while now, after having problems with my CAS, and getting that fixed, whenever I back off the acceleration (usually in 2nd gear), it makes a bang/pop noise from the exhaust. Only happens in 2nd gear, and only when letting it slow down in 2nd at around 2500-3000rpm. Anyone know what the problem might be? Thanks

Air leak in exhaust manifold/exhaust system wil cause a backfire.
