Review: Nice for the price - 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 Review: Great Replacement for Pocket Bikes - This is a solid replacement for the stock pocket bike exhaust. Installation is easy and we were able to do it without having to disassemble the bike! And that was a first. I usually have to remove the faring and gas tank or the fork. It comes with gasket and hardware, but did not include lock washers, which are critical for preventing the screws from backing out from engine vibration. ## Features - Less Noise, More Power - Expertly designed with a rear expansion chamber, this 2-stroke 47/49cc pocket bike exhaust can help lower noise while at the same time giving pocket bikes a power boost. - For Pocket Rockets & Mini Dirt Bikes - This mini bike muffler is crafted to perfectly fit 2-stroke 47cc/49cc engine pocket bikes.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice for the price *by S***G on September 10, 2025* 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 ### ⭐⭐⭐⭐⭐ Great Replacement for Pocket Bikes *by J***T on April 30, 2025* This is a solid replacement for the stock pocket bike exhaust. Installation is easy and we were able to do it without having to disassemble the bike! And that was a first. I usually have to remove the faring and gas tank or the fork. It comes with gasket and hardware, but did not include lock washers, which are critical for preventing the screws from backing out from engine vibration. ### ⭐⭐⭐⭐ It works on my super scooter *by C***W on October 2, 2023* It improved midrange power but I lost some top end. That said I’m very pleased with the results. Just be aware that this is loud so take that into consideration you don’t want to piss off the neighbors. About the super scooter it started out as a Razor metro Eco-smart. I replaced the 500 watt electric motor with a 47.2cc motor. I installed a 450 watt electric motor on the front. It’s a 2 wheel drive hybrid now. I changed the drum brake to a 180mm disc and added rim brakes. For comfort I added front suspension, suspension seat post and a comfortable leather seat. I’m 6’1” 175 pounds and this thing will do 20 mph going up an incline. ## Frequently Bought Together - 2-Stroke Muffler Exhaust Pipe with Expansion Chamber - Angled Design with Pipe Gasket - Compatible with 47/49cc CAG Daytona Pocket Bikes, Kids Mini Dirt Bike - Easy to Install - 49cc 50cc 2 Stroke Racing Engine Motor, Gasoline Engine Single Cylinder Pull Rope Start Motor for Dirt Bike Pocket Bike ATV Scooters, Pocket Bike Engine Kits - KAMIER T8F Drive Chain 116 Link Breaker Heavy Duty for 43cc 47cc 49cc 2-Stroke Pocket Rocket Bike APC Mini Chopper 50cc SSR SX50 Syx Moto Holeshot MotoTec Xtreme Xpro Kids Pit Dirt Bike ATV Quad Parts --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/96761421-2-stroke-muffler-exhaust-pipe-with-expansion-chamber-angled-design](https://www.desertcart.tn/products/96761421-2-stroke-muffler-exhaust-pipe-with-expansion-chamber-angled-design) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-24*
