<DIV>I've gotten a lot of recomendations to add a carbon lightweight 4-stroke pipe to our lineup so I'm starting to look at a 4 stroke pipe design. I have some questions:</DIV>
<DIV>1. What are the proper pipe inlet diameters that you desire on pipes</DIV>
<DIV>2. Worst reasonable case: how close is the pipe to the exhaust port</DIV>
<DIV>3. What max temperature at the inlet do you suspect (I'll be doing detailed research on this but want your opinion).</DIV>
<DIV>4. Is it possible to tune a 4 stroke at all, or is the muffling the only goal? If tuning is possible, how does this work?</DIV>
