hello all im looking a after market exhaust for my 660 raptor please help

 

This is a good pipe for the money, not a lot of power out if it (3.5hp gain still good) but great sound and much lighter then stock pipe (3-5 lbs lighter).

But if price is not a problem at all, definatly go with an hmf, they are great you can limit noise with a quiet core insert if trail riding or go all out in race mode. Great pipe and great power.
