Anyone have a problem with Loudmouth Exhaust

[pipes_ta]

I have had my Loudmouth exhaust on for about a year now and all of a sudden i notice a back fire when i let off the acceleration. Could there be a problem else where. I was thinking it could be becuase i lack backpressure thanks

LM1 or LM2??? I thought most LM1's do this.

That sounds normal. Mine did that only when I'd get on it good, then let off though. Under normal acceleration, it didn't do that, but under hard acceleration, it did. Its just blow-by from the higher revs. If it pops a little, nothing to really worry about.

^^^ Sounds like a normal back pressure pop...
