HMF or pure polaris pipes make the best power in that order. PP are hard to find as they are no longer made. You can run a slip on as your not going to find a head pipe that flows better then the stock one unless you get a Rath header. Its the only one that was ever made that didnt lose power on a dyno run that i have ever heard of. Just make sure if you buy a slip on that is made to run on the stock header or you might run into trouble with pipe length.

They make a excellent exhaust. There quality is excellent and so is there customer service. The Can-am factory racers use them.

But that doesnt mean its a good pipe for the predator motor.

well found 2 pure polaris slip on mufflers, made an offer on one and waiting to gear back!!

im not sure if what i had was the pure muffler or not.. it was black with out baffles and had a deep throaty sound.. i took it all off and switch to a full yoshimura system and i like it a thousand times better combined with a 155 main jet it absolutely screams.

all the polaris ones i have seen are alluminum with supertrape type dics's for baffeling, the stock is black and mine has the rear off of it. got a nice one of ebay for 139!!
