Not too sure about the Xforce cannons, but I'm running an Xforce oval muffler with custom 2.5 inch piping. The mufflers product number is MP-02 if your interested. the quality on them is very good and the sound is perfect for me. Its on the quiet side until you hit lift
thanx for the replies fella's & and1, thanx, just checked the MP-02, oval is 6"x10". atm im purchasing CAI. shortly after ill go with just the rear muffler change, just had a look at the MP-01 with the twin tips, liking the single tip MP-02 very much tho. u dont have a vid/pic or anything ?
