Sounds good Steve, Looking forward to the results. I have done a lot of research on 2-cycle exhaust for an expansion chamber design. From what I've read at the very least the engine should run a little cooler since it would be relieving the exhaust pressure a little easier. I'm planning on the exhaust baffles out for the break-in period. If anyone thinks this would be a bad idea let me know as I plan on wrapping this project up in the next month if no problems arise.
