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

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.

This project was perfect

Product fine, but there was welding spatter all over pipe that should have been removed before finish painting. Had to clean and re-paint. But still a good value!

fit my 49cc mini pocket bike

Would give zero stars if I could. The muffler is not a muffler, it's just a larger piece of pipe with end caps. Does not muffle the exhaust at all.

Got it for a 49cc scooter but didn’t fit

Great exhaust system for small performance engines. I used this on my 52/49cc (you never know with the cheap Chinese ones) engine swapped pocket bike. I put the engine I used in the review pictures. This exhaust system for almost perfectly after cutting the hanger off of it and this bike is very very small so that’s impressive. As you can tell by the custom engine mounts, I’m no welder or mechanic. So I could have made it fit with some more “custom” work but it is almost all the way on, very very minor exhaust leak. Build quality has been good so far, will update if that changes

I bought this pipe to put on a 66cc motor kit for a mountain bike.i had to cut the flange off and reposition and make a bracket. The expansion chamber is a little small but it made a difference in low to midrange power and sound on the stock engine. For the price it was well worth it as just a basic mod. But don't expect 35mph without some porting and other work. Also it is slightly loud, but it sounds like a little dirtbike.
