This pipe is a piece of crap. Apparently, MLM doesn't know anything about how wave form and gas flow works when going around sharp corners. The header pipe joint at the diffuser cone looks like it was kinked in a vice. Graham Bell would be very disappointed in this abomination. My taco rating is two taco bell tacos left in the back of a Subaru Brat for three years, that the rats won't even touch. The welds are pretty, though...

Intramotor Gloria Scout, M01, 12mm carburetor and intake, aftermarket carburetor slide, removed some screens from the filter and the sound deadening tubes from the air-box.
before buying, i knew the rear mount was on the wrong side for my frame. i'll make a bracket before i continue tuning.
the good: header angle is perfect. center-stand and pedals clear the pipe. idles stronger. take-off from stop to low rpms is waaay better, hits the pipe when nearing previous top speed of 25mph. I have only just begun tuning, so i dont know how many MPHs i'll gain.
it just mopeds: had to grind a lot of material off the header bracket to clear cylinder fins. DIY'ed a spacer to bring the pipe down so the header would clear the cylinder fins as well.
Sick and twisted is right. 
better performance in every respect.
