| |  SBP"s exhaust chamber upright position
I made my pipe in the upright position.I needed a piece of copper in the 45 degree without one end flanged.So i cut a piece out of an old set of handlebars. I also went to tractor supply and bought a $3.00 muffler and bored out the end a little and it slide right onto the silencer of the pipe.Drilled a whole and put a small bolt on. It did help with the popping noise these pipe's make.Its still a little loud but better.I was going to get some header wrap but its like $30.00. Any ideas on me not burning my leg?LOL! |

That looks sweet man, I like that - much tidier that way and ya don't need to worry about the rocks like I do lol
What about some expanded aluminum mesh as a heat shield? It comes in a buncha different styles... I dunno if you've a metal shop supply nearby, but I've seen it at good hardware stores too. It's real easy to work with... |

I rode it today with shorts on and its really not a factor. I mean ....I guess if you want to burn your leg you can. I still think some header wrap would be the best and easy, probably ugly,but also make it not so loud! my wife said it looked better down under the frame.I told her it looks more like a dirt bike. Heck women don't know sh**! LOL! |

Anyway here is a good wrap for your set up...BTW your plugs will burn if you have the mufflers too close...

If you use that black header wrap, it gets black stuff all over you every time you touch it!!! |

Mote places that supply header wrap also sell a spray on clear coat that will help stop the color from rubbing off on you. It really is made to stop the wrap from shedding fibers and seal it. |
