    I have an "80"cc engine kit from bikeberry on the way to install on my occ chopper. I am courious what size is the exhaust tubing?
    Im guessing 1" or 1.25". from pics.
    Im probably gonna fab up my own exh. im just trying to get a headstart and have everything i need to get it going sooner.

    20mm pipe, 18mm flange

    and 15mm outlet

    i suggest just mathcing all the ports as much as possible for good flow upon the stock exhaust before going custom, but that's just my opinion

    thanks! I have to move or bend the stock exh. to fit on an occ stingray from what i have read on here. im just looking to make it look something like this i might even just buy it.

    thanks again for the measurements!
