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

Bolt is short, everything else is awesome

El tubo de escape si encaja con una bicimoto con cuadro montañera normal. El único de malo es el perno hexagonal que trae es muy corto, debe ser más largo pero no es algo que no se puede soluccionar. Y he notado un ligero aumento de potencia.

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.

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

great product quick delivery very happy

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

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.

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
