## Description

Is your pocket rocket lacking power and sounds just a bit too noisy? Mini bikes may work great the first time you take them home. Yet as time goes by, you'll start noticing certain issues that affect the bike's overall performance and output. There will be times when you feel like you're not getting enough power from your pocket bike. Sometimes they sound pretty loud, which can be quite annoying for fellow riders and neighbors. Luckily, there's a simple upgrade that can help you with both problems. This 2-Stroke Muffler with Expansion Chamber by WEIYINGSI is just what you need for increased power and reduced noise. Some pocket bikes don't come with mufflers, which is why they can get pretty loud when they run. Installing this Muffler on them can help dampen the sound the engine produces. This also helps increase the bike's performance and horsepower since the pipe allows for better Muffler flow thanks to its expanded chamber. These Muffler are designed to fit pocket bikes and kids' dirt bikes with 47cc/49cc 2-stroke engines. They're pretty easy to install as well and come with the necessary accessories like a pipe gasket, additional bracket, and screws. The Muffler also feature an angled design which helps make installing them a lot easier.

## Questions & Answers

A: no

**Q: Does this fit mototech 49cc gt? Pocket bike**
A: yes

**Q: Will this fit a mototec 50cc demon?**
A: Not sure, but if you study the picture and make sure your bolt holes are the same you can bend this exhaust pretty easy to get it to line up. Mine would have come out my seat if I didn't bend it to fit. Clamp down 1 side of it and stick a pry bar , pipe, tire iron in there to bend it just go slow so as to not over bend it

**Q: Why wont the items i want ship to my location**
A: Please concact with Amazon service

5 stars for the price. How well it fits depends on how good you at bending with a torch. Will need some deburring at the flange. Fits my 36v/50cc mototec conversion perfectly
