What is the best sounding,quietest slip on for this. I want something that sounds good and is not verey loud.

 

Not sure which is the quietest but, my buddy has a full system hmf on his p650 and it sounds great,it is a little loud though.I have the big gun on my 02 p650,sounds good not as loud as the hmf but has a nice deep tone.Not sure if I would recommend the big gun because mine is falling apart,has been since about 3 months after I got it.These are the only pipes I have heard on the prairie,hope this helps.

 

I have heard pro circuit makes the 496 pipe; hp gains but @96 decibels. FMF makes the "Q" series, which means "quiet". FMF also makes a "powerline" series muffler for utility quads, I believe it uses internal deflectors instead of packing to reduce exhaust noise. I have an HMF full on my p700, and it is not for the stealthy. (LOUD!) hope this helps.

 

If I was in the market for a new muffler and wanted quitness along with power I would take a hard look at the FMF Powerline muffler.
