Pop when letting off?

[andy_09]

occasionally my 1100t with mbrp trail can will pop when i let off and the motors slowing down, anyone else have this? i didnt replace the exhaust gasket when i installed the mbrp but with it idling i cant feel any leaks like its sucking air in and igniting making it pop, kinda sounds like when you shut it off and it makes that whoof noise, one more thing i mostly noticed it doing it when going slow on the trails like 5500 rpm and below like it was loading up

Mine popped with my exhaust last year and pops with my new exhaust this year. I am not to worried about it. If it lean pops under power then I will be worried.

Mine is lean popping under power. Jim told me to check lines for holes but I can not find any so I am stumped now. Will have to call and pick his brain.

At low elevation? Are you sure it is not over revving? Looks like I need a o2 gauge so iam sure of my tune.
