Our KRX 1000 added a mbrp muffle and new muffler gasket and and did reflash,and we are still have backfire when deceleration. Does anyone know what the problem could be????

Who did your tune ? I drilled out my cat and a tune I’m also having backfire issues. Mine also appears to be running lean looking at the inside of the tail pipe.

Alba racing did the tune for the slip on muffler.
