What is the best expansion chamber that won't break the budget? I am looking for more speed, the bike already has plenty of torque.
Thanks!

Depends on if you want acceleration to go with that speed... I'm going 43mph with the 44 tooth sprocket that came in the kit, but it takes more than just a good expansion chamber to do that...
For the good expansion chambers, there's only 2 of them you can buy for these that I'd recommend, and I'd still recommend modifying a dirtbike pipe over buying a modified pocketbike pipe, but the SBP pipe performs and so does the Snake pipe sold by Arrow Racing. They're both modded pocketbike pipes, but they do work well.

A cheap eBay Dirtbike pipe for a bike in the 65-90cc range.
Look around you can probably find one for around $40-$50.
Then use this to mount it to the engine:

-One of the "Fire Breather Header Kits"
Cut-cut-weld-weld.
If you don't weld, take it to a muffler shop with the exhaust, the manifold parts, and your bike. Probably end up spending another $40-$50 to have it cut and welded to fit the bike.
$80 - $160 depending on your fabrication proficiency and eBay skills, and hands down the best exhaust setup you can run on these engines.
