currently has a stock muffler with an aftermarjet larger headpipe. I was looking into getting a slip on or a whole system, or even ripping out the end cap. I was wondering if anyone had ever done that before and if it made a difference. Also what is a good exhaust system for thses quads. I am watching an HMF on ebay that is just the muffler.

 

The HMF is a good way to go and the BIG GUN is a good suggestion, fmf might have a good pipe put i dont hardly see them on a 300ex seen ALOT of DG's but i think big gun or hmf is the way to go, if u allready have a larger head pipe just get a slip on save on some $$$$$

 

hey i would go fmf megamax 2 with a k@n filter

 

One of my freinds has a white brothers and its pretty nice.

 

FMF Mega Max II witha k&N will really improve your setup, thats what I did and you could pull wheelies all day, and climb hills till the cows come home... lots of torque
