Cheap upgrade!

[lilchunkyboy]

Hi, I have a 80cc 2 stroke, everything is stock except for chain. It’s running decent, but I kinda feel bad for it, I need to upgrade to higher performance parts. I am first thinking expansion chamber, but I’m aware that some expansion chambers are junk. Can someone suggest me a really good expansion chamber, for a relatively cheap price. Price range (50 to 100 $) it doesn’t have to be a expansion chamber but I’m leaning towards it, just need a first good upgrade to increase performance. (Located in aus)

The words “cheap and good” rarely go together, a good quality chamber and silencer can be had from eBay for around $100, on mine I welded a stock muffler on as the silencer, the best pipe will be the “fatty” type, guys on the forum that race use a chamber from a kx80, cr80 etc. They modify them to use on a bike.

I’ve seen the cheap banana type exhaust pipes on eBay for 30, 40$, but they don’t look that appealing, and barely add any performance, definitely want a mz65 pipe.
