I have a 2002 raptor with a pro circut T-4 which I love but it is extremly loud and I want to quiet it down I was thinking of putting an fmf powerbomb header on it because it is supposed to make it quieter. Has anyone used these and did it make a difference. I love the power but the sound is causing difficultys in my riding area. Ive tried the quiet core and it made no difference. I was thinking of trying to buy another pipe manufactures quiet core and trying to adapted it to my t-4 Any thoughts would be great.
