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

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

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 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.

This project was perfect

Was broken from the time I opened it. all welds are splitting and are not even good welds. Would not recommend buying at all. also it did not fit product specifications.

Is little bent

Nice quality, increased mid and top end significantly. For the price you cannot beat it.

Good quality
