Hey guys I recently joined the site and aquired a 2005 LE Raptor 660 and had a quick question pertaining to exhaust. My Raptor currently has an HMF quiet race series full exhaust on it which I like but after seeing the Monster dual setup Im thinking about switching. My question is is this a good move or no. Right now the quad is jetted for the K&N and exhaust (according to previous owner) so if I get the dual setup would if have to be rejetted? And if I did decide to buy the Monster what could I sell the HMF setup for (its in great shape)? I have been trolling the site for a little bit and am learning as I go. Thanks in advance guys. Matt
