Default Re: carb as a muffler?

i can,t speak to much for 2 strokes , but putting a valve in the exaust system will make your back preasure a variable , making it next to impossible to achieve an ideal jetting setting .

you want your exaust system to flow at a constant .

i think you are better off just experimenting with different size pipes and muffler tips and baffles .

BarelyAwake has a good thread on a remote airbox , which he noticed quieted the engine down some .
