Bike backfires into a quite muffler = you CAN'T hear it
Bike backfires into a loud muffler = you CAN hear it

Bike most likely has always backfired a little as is very common with these engines. No biggie.

When it backfires it sounds like your next to the muzzle of a gun going off. Its far from little

Usually not a bad idea to put a light, uniform film of Permatex Ultra Copper on the exhuast joint. This will seal up the joint and also prevent the mufflers from seizing to the headpipes making future removal easier.

If you hold your hand near the connection with it running do you feel any air, blow some cigarette smoke at it. I've put 400 miles on mine since installing last Wednesday and I can't get mine to backfire at all. I don't have an aftermarket a/c or tuner though.

I hope it's a Kimber 1911, they sound great :-) Seriously, I had the same problem when decelerating. I did as suggested by the PC guys and enrichened the mixture at 0% throttle. No more popping or backfiring.
