JRL 44mm Black Half Moon Muffle Exhaust Pipe With Silencer 49cc 60cc 66cc 80cc Motorized Motorised Bicycle Bike Engine Motor Parts

I am VERY impressed. Though there are a few scratches on it and the welds are far from perfect, this item is great value for the price. Sounds great and not too loud. Looks good. Fits my bike perfectly. AND more power! I'd say about 20 percent. Allows my motor to breathe well. Very happy, I'd say BUY IT!

Haven't install yet.My factory pipe broke in half and I gained 5mph but now way too loud. So I bought this muffler.This one has to be alót quieter. (isn't broken) I don't care if I lose little speed. Paint surprisingly nice, decent welds. End of muffler seems off center a bit when I look thru hole. Am sure not all mufflers will be same. Overall nice. Smaller then I expected. My guess, just under 2 feet in length

The media could not be loaded. Sounds fairly quiet. Its about as loud as a stock exhaust with an extra hole drilled next to the stinger. Only ran it around block so far, i did notice slightly more power. Its definitely better than stock muffler. Better low to mid power. Have yet to see how the top end performs. Ill have this updates once i swap to a better carb. This one is clogged.

Muffler does not fit try to bend it to make it fit it does not fit

This is supposed to be a quieter muffler for your bike it is not that at all I think it's louder than the one you get with the kits after it's installed there is no room for any type of adjusting so I say it doesn't do anything it says it does would not recommend

Initially the muffler flange didn’t sit flush with the engine and the chamber was in the turn radius of the front tire. I had to remount the engine and change the position of the chain tensioner to get everything to fit and run. There’s a noticeable increase in noise and bottom end power. I haven’t gone further than down the street for a test run so I don’t know if there is any gain in overall speed with WOT

Loud. And allows engine to breath. HP gain is noticeable. Worth the money with out doubt.

You can clearly see the deep gouges, their way more then some scratches, the expansion chamber is very small I wish it was twice the size. But for the price it is what it is. Definitely better then the stock by far.
