Tired of that stock muffler not giving you enough power, but a standard expansion chamber won’t fit on your frame? With the new BBR Tuning DELUX High Performance Expansion Chamber not only will you get the performance boost you’re looking for, but you’ll get a better fit than ever.

Stock mufflers keep your bike from running at full performance because of their built-in reed. With this expansion chamber there’s no reed holding you back from getting maximum performance. In addition, its extended length helps you expel more exhaust from your engine. With its banana expansion chamber, the exhaust is circulated around the chamber and smoothly flows out of the chamber instead of being shoved out like in stock mufflers (which usually creates build up in the engine).

Because these mufflers wrap around your frame and come up around next to the engine, there’s no more fear or bottoming-out and scraping or breaking your muffler. Especially helpful for motorized chopper bikes and motorized low-riders, with this muffler you’ll be able to expand your customization options wider than ever. But don’t let that stop you from using it with a 26” or 29” bike, because these mufflers are compatible with nearly any bike and any 2-stroke motor: 48cc and 66/80cc alike.

With a boost of performance and a whole lot of style, the BBR Tuning DELUX High Performance Expansion Chamber is everything you want and need out of a high performance muffler. Whether you’re looking to add some added speed and get a smoother ride, or if you want a muffler that’ll fit on your low riding bike, this is the muffler your engine’s been waiting for.


  • Color: Chrome
  • Compatible Engine(s): 2-stroke 48cc and 66/80cc engines

WARNING: Bicycle engine exhaust mufflers becoming increasingly hot with use. Because the expansion chamber of this exhaust sits next to the cylinder head of a bicycle engine, please use caution when operating a bicycle with this muffler installed. Wear full-length coverings for your legs and do not intentionally bring your legs in close to the engine/muffler.

Best pipe, hands down

Pipe fit bike frame perfectly! Max speed 42 mph, with porting of head and installed pipe, w/30 tooth sprocket. Also, Welded muffler on pipe, little quieter, not much! All in all, I love the thing… Ron Mac

BBR Tuning Expansion Chamber makes a huge difference! I built a 48cc Grubee Skyhawk motorized Huffy Cranbrook and have been riding it for 5 years now. I kept the motor all stock until just recently. The only modification I made was the BBR Tuning DELUXE High Performance Expansion Chamber. It bolted right on. Installed in less than 5 minutes. The big difference this little muffler madewas almost life changing for me. I am now addicted to modifying these little engines. The response of the bicycle is so much faster. Also, the overall top speed increased drastically. It almost feels as if the motor can ""breathe."" With the purchase of that pipe, it has led me to building two more bikes, and now I build custom motorized bikes on the side. Every bike I build is equipped with this muffler. Best purchase I have ever made, hands down.


Vroom Exhaust is loud and adds some extra kick for a motorized bicycle.If you like noise you will enjoy this.It bolts right on but depending on how your bike is set up, the exhaust tip runs very close to the gas line leading to the carburetor.Had to use a zip tie to pull the gas line over just enough so the hot pipe won't rest on it.Had no area on the engine to secure the hanger and bolt you see in the picture??The gasket to the engine head should be included with the exhaust unit and not as an add on
