I got the idea of puting a pro circuit ti4 muffler on my fourtrax 300. i can get one off a crf450 honda d-bike for about 70 bucks and i would like to cut my muffler off and weld this one on it. or should i make a whole new whole new header for more power? would this work do you think? i want some more power and and im bored. i cannot find keihn jets anywhere for it. the only jets i can find are some cheap rd jets, i need the slot head jets. thank you, Jeff
