I have a relatively stock 1980 Motomarina Sebring with MO2 motor and am undergoing some performance upgrades. I'll be updating my SHA 14.14 carb to an SHA 15.15 and debating between the Metrakit MK3 exhaust and the MLM Peoples exhaust, as they seem to be the most popular for this engine. Already geared down my sprocket to 34T which gives me great take off the line. Currently get just under 30mph and hoping to get between 35-40mph top speed.
Does anyone have any experience with either or both exhausts? Pros and cons of each? Which will garner better top end performance over which will be overall quieter (somewhat a concern)? Any other exhausts I should consider?
I'm newer to Mopeds in general, so thanks in advance for your thoughts! (edited)
