Description

Looking for even more power out of your 2-stroke motorized bicycle? The Speed Demon High-Performance Expansion Chamber drastically improves the stock power bandwidth of your 48cc or 66/80cc 2-stroke engine.
This pipe improves the use of any leftover energy from the burnt exhaust exiting the cylinder which helps fill the cylinder for the next cycle. This, in turn, increases your motorized bicycle engine kit’s low-end acceleration and top end speed. All this is done with a muffler to stifle the sound of the exhaust.
Easy to mount and compatible with nearly and 2 stroke engine out there, the Speed Demon High-Performance Expansion Chamber exhaust is perfect for those looking for more performance out of their motorized bike without creating too much excess noise.

This Expansion Chamber with Muffler will enhance your power output by expanding the volumetric efficiency 2-stroke bike engine. In addition to adding a boost in the top end speed, this muffler improves the use of any leftover energy from the burnt exhaust exiting the cylinder. This helps aid the filling of the cylinder for the next cycle, and all is done with a muffler to stifle the sound of the exhaust.

not bad It took a couple pie cuts and some bending and welding to get it to fit properly, but it looks and sounds good:)

Works like a champ Bolted right up to my 66cc and smoothed out the feel through out the entire power band. As always the fellas at Bike Berry were awesome! Oh yeah so was their pooch Sprocket!

Glad I bought one I popped this on a stock 66cc, and got instant results. Better low end and a cleaner high end. Glad I got this one :)

some modification required When I bought this I thought it would fit easier than it did. I had to fit it in a jig and heat and bend it because it had no bends whatsoever and it was directed into the frame.After doing that it directs the exhaust directly toward the pedal crank. I have a cruiser type bicycle.

Quieter than I thought but totally worth the buy. ! I was scared after buying it thinking it might not clear the pedal crank but Ironically it fit way better than the stock pipes and I have just your typical straight V frame shape mountain bike that the kits are designed for....but all in all its a great pipe if you want something that will fit, look awesome and run quiet.
