CDH88 Muffler Exhaust Expansion Chamber Muffler- Gas Motorized Bicycle … (Colorful)

Nice pipe good quality, will need a carb rejet but does make a big difference for the money, highly recommend this pipe

GREAT

Welds gave out after a handful of rides this is junk

Keep this in mind if your using a cranbrook you may need to use a wide crankset kit for the motorized bike luckily it’s on Amazon as well but other than the crankset the mounting brackets seem kinda flimsy and I might have to make my own custom work on it but definitely gave a little boost in power otherwise I’m a little disappointed in the fitment of the peddles

Its a true fat expansion chamber. Fits perfectly on a Scwhinn OCC CHOPPER. Without modifications. It did however break it's rear weld in two days. When it does the gasket with bust, you'll risk your piston at high speeds. I had to use permex right stuff red 90 minute gasket maker. Keep in secure and I had to use a hose clamp to secure it. Be sure you use high temp thread lock on your bolts.
