Thanks for the response.
I've been struggling to choose an exhaust. My preference is for the MLM people's pipe but I have read that it's hangs low and is too easily scraped. I don't suppose it's been altered since its debut to fix that issue?
The circuit pipe looks like a constipated python.
Is the next level pipe sufficiently free-flowing to get me to 40mph with malossi 70cc kit + upgraded carb?
