Motorized Bicycle Kit with New Style Muffler

[rohmell]

Has anyone bought an motorized bicycle kit with the new style muffler?
How does it fit to the contours of the bicycle? It looks like there might be clearance problems if the engine is mounted too high in the frame.
Looks like there is a nut/bolt on both sides for easy disassembly and cleaning.
Are there any pics of MBs with this type of muffler installed?

I don't know, this is the first time I am seeing a kit with this type of exhaust from two different eBay vendors:

Sry, no experience with it, but it sure looks nice!
I'll bet it's an improvement.

From the look of the exhaust and the long curve of the pipe before it reaches the muffler, it looks like it would sit underneath the bottom bracket of the bicycle, but I plan on using a small frame with 24 inch wheels, so I want to get an idea of what a completed kit on a bicycle looks like.

Otherwise, I will get a kit that has a 'regular' exhaust and kill switch, because this kit has no kill switch included, so that is an addition extra item that has to be obtained and mounted somehow.

This is the style of muffler that kits came with 3 or more years ago.

It looks like Simpson Motor Bikes is still selling some of these old kits.

Here are some pics from http://www.simpsonmotorbikes.com/picutres.html

Thanks for the pictures. Looks like a muffler clamp would have to be a mile long to secure it to the frame.

Those pipes are from the 'old old' kits.

Re: MB Kit with New Style Muffler

these mufflers are sold as aftermarket parts as well now. there are two versions of them. all of the ones pictured are the low hanging version. not sure what is good about a muffler hanging so low other than a longer header. on a smaller frame I would worry about it dragging. there is also a version where the head pipe is the same as on the cat mufflers. both versions feature a removable baffle for added performance. I have used a muffler with the baffle removed (not this one, a black cat actually) and found that it performs similar to an expansion chamber. can't say its exactly the same, but I did have added torque on hills and would feel the rpm's decrease and then increase again, just like an expansion chamber.
