A few months ago, my son bought a brand new Honda Monkey. Neat little bike. Well, being a fuel injected motor, the exhaust system goes from the head pipe, under the engine, through a catalytic converter, then makes a u-turn and comes up, makes another bend and then out to a cannister muffer out the back. Nasty thing, but the bike had a nice exhaust sound, more of a blub blub blub, rather than a rat tat tat. Well my boy bought an replacement exhaust that has no cat but looks almost stock. Sounds the same albiet maybe a bit louder. I took the old one of course. So today I spent the day cutting and welding until I came up with a something that resembles an exhaust system. And you know what, it goes blub blub blub. (My CT has a YX140 in it). I sprayed the exhaust with some black Hi-temp and will post a picture tomorrow. May not be the trickest system, but the price was right.
