Description

Need an exhaust for your 2-stroke motorized bicycle that’ll give you performance without making too much extra noise? Then the Speed Demon High-Performance Expansion Chamber is exactly what your 66/80cc 2-stroke engine needs.
This Performance Expansion Chamber mounts the exact way its bigger banana expansion chamber does, all while increasing low-end acceleration, top end speed, and keeping your bike quiet with a baffled muffler. With its built-in expansion chamber and shorter muffler, your motor will get better airflow and increase your bike engine kit’s performance.
Long lasting, easy to install, and compatible with a huge range of 2 stroke engine kits, this Speed Demon Expansion Chamber and muffler will out-perform your stock motorized bicycle engine kit muffler like it’s nothing.

Motorized Bike Kit Performance Exhaust Muffler Upgrade with Expansion Chamber is compatible with any 2-stroke 49cc/66cc/80cc Bicycle Engine Kit. Replaces stock muffler with same bolt on pattern requires no modification. This performance muffler has a built in expansion chamber and shorter muffler allowing for better flow and engine performance.

*Note* This muffler does not come with a gasket or specific mounting hardware. However, your existing gasket and mounting screws should be sufficient to optimally run this muffler.

Performance speed demon muffler with expansion chamber

I love this muffler it's giving me horse more horsepower more acceleration and more top end speed it's smooth out the vibration and it's a lot quieter than it was before I love this muffler it's the best and also looks really cool highly recommend replacing your stock little Chrome muffler with this you will be happy

I'm not sure how much it helped to be honest.

I chopped it off at the end to make a non muffled banana pipe. Way more power. Way too noisy now, but I'd rather ppl hear me. It's safer.

I cut this pipe at the bend to re-orient it for my 50cc engine. On this engine power really kicked in from 7,000-10,000 RPM. It has a nice motorcycle-like idle and sounds much less like a weed-whacker. Good value, only downside is I noticed the internal pipes connecting to the expansion chamber have some nasty burrs from when they were cut and assembled. The manufacturer should take the extra 10 seconds to de-burr the pipes.
