Ultra- Q exhaust popping/misfire sounds???

[redrocker07]

I have an Ultra-Q muffler on my '07 Phazer and it seems to be getting louder than it was last year and now I'm hearing a popping or possibly a misfire at low speeds- anybody else have this issue?

Yes mine will pop occasionally on decel.I didnt use a clamp just slipped it on may be a slight airleak but really nothing to worry about.I know on my quads a pop every now and then is a good indicator the AFR is right on.More than one.Like Boom,boom,boom is almost always a airleak.

Check your connection at the motor end. A lot of people have have a cracked exhaust header.
