Anyone using this expansion chamber? $27.99?

[burrus]

Just saw this and was wondering if anyone has any experience with it. Seemed like a pretty good deal for $27.99 Just starting my new build with a
SkyHawk Angle Fire GT5A 66cc and I used the muffler from that kit on another bike.

I have that type from arrow motorized, better than stock. I'd save a little more and get something bigger if I were you, I'm already looking for another to install.

I have one like that, also from Arrow. It works fine, provides a very noticeable boost in bottom end and midrange power, and has proven to be durable. I've had it on my bike for a couple years now, and couldn't be happier.

"ALERT" I wouldn't buy anything from bicyclemotorworks.
