FVRITOPerformance Exhaust Muffler Expansion Chamber Pipe Silencer Gasket for 2 Stroke 50cc 66cc 80cc Engine Gas Motorized Bicycle Motor Bike Black

Little tip use more support for this if you use a muffler the little metal tab used to support the extra weight broke on mine but it worked perfectly added some power to my 100cc and worked well till it broke so ima just fix it with some welds

Seems to be a really good pipe my bike runs great sounds very loud. Remember you'll probably have to do some adjusting to get it to fit on right but besides that it's a great pipe for the price and the performance

Sounds and looks a lot better than the stock pipe. Mine came with a pinhole where it looks like they blew through the weld on the bracket that attaches to the crank case

The gasket that comes with it was folded and is now useless. Normally i wouldnt care but on my first ride my gasket blew out. And having that other one in working shape would have been nice. On the upside if you cut the stock exhaust leaving about an inch it slips into the stinger. Little relief slits need to be cut around the end so it can be secured with a clamp. I used the ring used to secure the carb to the intake because i had an extra. Conversion took about ten mins.

Looks great super easy installation rather loud but I've altered this exhaust and made it much quieter an still performs spectacular

This exhaust is awesome and leads to a lot more power. But using it in the neighborhood is just too loud so we reverted back to the original exhaust.

Asked seller if this will fit on a phantom 85 directly and he said yes. Well it didnt the flange is too small... Not happy.

Not gonna lie, for the price, I didn’t expect anything other than it looking cool but it’s loud af in clean way, and definitely added top end power.
