Awesome sound and adds some speed to the pitbike!

I love FMF and have it on all my bikes so figured I’d add it to the pitter and it’s awesome. Added about 5mph to the previous top speed and sounds so much better, but it is loud.

END Exhaust

I ordered this and it arrived a day earlier than it originally said it would be here. Very easy to install took me about 15 minutes. Does not come with heat shield but the one from stock exhaust fit right in. Only issue is that the 2 bolt holes on the muffler didn't line up completely perfectly for me. One bolt went right in no problem and is very sturdy with just the one. I can still the other hole bigger to get the 2nd bolt in but I'm too lazy lol

Arrived on time and fits the pit bike

The product was delivered on the expected date. it is light and easy to install on the Honda 50cc. If you need a muffler replacement at a reasonable price i would recommend this one for you.

FMF power core 4

Quick and easy bolt-on performance upgrade. Looks and sounds amazing! The XR 100 sounds like a "big boy bike" now.

A: The FMF exhaust will be a good options for boosting HP. How much HP will be gained will depend on other modifications done to the XR100. If the XR100 is stock, You will notice a mild gain. Jetting may be required.
