pipe had to have mounting holes moved a little, makes extreme power in hits super hard on top end, sound is disappointing though compared to the proma zombie unit

Need to modify header to mount (so no 5 stars from me), but maybe that was just unique to my bike...Great Top end pipe though, you'll want to lighten weights after as it sucks the life outta your low end.
This pipe, uni pod filter, bx31, upjet, 5.4 gram weights=38 mph on the flats. I'm happy.

I strongly recommend the Weak-Ends unit if you can swing the cost over the readily available alternatives - bolts right up with no modification, sounds great, high quality welds and paint.
Pipe rips from 25 to 35mph on my stock 49cc with a AX31 / 27mph to 45mph all day with an BX31. Uni filter, no other mods. Minimal loss of low end vs. stock with AX31; more obvious as expected with BX31

Very well built, keep your center stand, even has a mounting tab for your rear fender brace!
On a stock cylinder has no low end, takes forever to hit the powerband even with lighter weights in the variator. Best pair this with a kit.
decent pipe
