Hey everyone im new here and need some help/opinion regarding my 01 raptor 660.. the previous owner did something to the exhaust and its running un ordinarily loud. it has a pro circuit t4 muffler. after taking the muffler apart, i learned that its hollow.. i assumed they usually have wrapped fiber glass in them? so i put some fiberglass in around the metal holed cylinder case inside(i dont know the specific name of the part). it did very little to quiet it down..i noticed with ordinary mufflers they have a cap at the end of the muffler, my raptor does not have one. could this be part of the problem? and yes, i understand no matter what i do to the raptor will be loud in comparison to my blaster but im just trying to get it to a berable level. thanks
