well guys i scratched the tractor pipe and ordered an HMF this morning..should be here friday or so cant wait to finally ride again..its only been since new years..AHH the joys of being employed and makin money.
UPDATE, i did infact get one, and finally found the right jettin and the thing has a ton more low end and a very nice SOUND. the rhino has an even better sound with the HMF very deep when you stomp on the throttle and it also woke it up including the jet kit. i would highly recommend the pipe/jet kit too all rhino owners that want to be the offical tow wagon like iam..DAMN HONDAS AND PO-PO'S!
I just put the HMF Ironman Carbon Fiber on my 400EX...AWSOME! really throaty and gives it lots of power...I was really surprised at the power actually. Without the qiet core its pretty loud, with the quiet core its supposed to come in somewhere areound 96 or 97 decibles.
