The Villers 198cc I used to have, ran much hotter (tested temp) with a more basic exhaust, whereas the expansion chamber exhaust kept it cooler.
Maybe it would run better and cooler with an expansion chamber but I don't think it would suit the build at all, besides I quite like the look of the stock exhaust, and while I know my back has a rear disc brake but that had more to do with budget (didn't wanna pay for new hubs).
