nice, where'd you find that at again? What kind of difference does it make besides sounding nice?
Cool stuff. ;D

Nice, nice, where did you get it?, ;D Hope you explain us how does it works and sound, and how hard it was to install, looks like it could use more hangers, but it sure is a looker  |

Yes, please tell where you got that from... That would look sweet on my red Ruckus.  |

The muffler and pipe are from my friend Waynes scooter shop. Its a prototype made by his friends in Taiwan. Its anodized? aluminum and comes in a few different colours. It was originaly made for a 125cc 4 stroke scoter (not sure which one)but works on my 50cc just fine. The only prob was the pipe was not made for the Ruckus so it required some bending and cutting to make it fit. It seems to have lost a very tiny amount off the line and on the hill climb but SAILS on the downhill even more than the stock muffler did. I think the reason for these two changes is because the pipe is a slightly larger diameter than the stock one. I'm happy with it. It sounds like a real honda motorcycle now. I'm gonna check the spark plug tomorrow. I'll let you know how its burning.

Well i know your ruckus is not feeling that good but what is the story with your exhaust, did it work at all and if you would recomend the pipe  |

a bathing ape (to be exact)
I ended up taking the muffler off as I lost too much overall speed. It was considerably lighter than the stock one but I think the pipe coming from the motor to the new pipe was too wide in diameter. Therefore not enough backpressure for the motor. I still have the muffler and would like to retry it with the propper diameter pipe but I cant find one. Anyone out there wanna make stock diameter pipes that we can throw various aftermarket mufflers on? I've asked around but you need special gear to bend tiny pipe like that without pinching it.

As crude as it might sound, we use to fill the pipes with playground sand and put a cork on both sides and bend away, as good as mandrel bend, does not work as good on bigger diameter pipes ;D ;D

Yes, I've heard of this system but I was thinking more of someone who has access to a pro system and could knock off a few of them to sell wholesale style.

I don't get what the sand and corks would do to prevent pinching. Please explain...

on the subject of pipes that would work well for the ruckus, I was considering somthing like an FMF pipe off a Honda XR50.. I think it would be more correct for the ruckus motor than a pipe built for a 125... however they arent cheap.. and I dont own a ruckus to test pipes on..

Yeah even if you had pipe the right diameter, you'd still need a Ruckus to make the correct bends with.

Ok this is kind of hard to explain so bear with me, when you bend thin tubing, either by heating it or by bending it with a hydraulic press it will probably collapse or narrow at the bend (look at a factory exhaust in a car), making the diameter of the pipe at the bend smaller than the rest of the pipe, by filling it with sand you are preventing this to happening by making it act like a solid rod not a hollow tubing, this method is use a lot in fabricating small amount of bend tubing like in headers or kit planes, obviouslly the prefer method of bending tube is in a hydraulic bending machine, becouse heating and cooling a tube to bend can alter the physical properties of the metal. Ruckass, if you intent to do less than a hundred exhaust tubes, then fabricate a jig and use the sand method with a tube bender, it will work just fine, just use a tubing of .065 wall thickness, with and internal diameter of 7/8 (factory size) of low carbon steel DOM (drawn over mandrel), more than a hundred and then you probably will have to redo the jig every 100 or so copies |

Think of it like a garden hose, with no water, it will be hard to bent it smooth, if you add water it is very easy to get a smoothy bent  |

Thanks Chanito but I understand the physics behind the pipe bending and the sand filled method. My point is that you would need a Ruckus to model the bends around the motor and wheel etc. I think if you didnt have a Ruckus to use as a model then you probably could not make the exact bends and the pipe would end up sending the muffler in a slightly crooked direction. It happened with the pipe on my Ruckus and the muffler ended up going slightly towards the tire, not straight back.

The explanation was intended for pain merchant, he asked for it, about the ruckus, yes and no, it would be best to have the ruckus to prevent any problems, but all you should need is a ruckus exhaust to fabricate the jig, you can make it out of 2x4s and plywood, but if you want to do a lot of exhaust then one out of pipes and steel channels is a must
