This is tough to review bc my 50v av7 isnt tuned at the variator bc that damn cheek is a bitch to remove. You will need the pedal extender. THE PIPE is amazing quality, there are 2 restrictors in it; one is the washer bullshit but the other is in the muffler but you need the 10mm hole (just remove the tack welds and pop it out then remove the ass end cap to have the 10mm exit but get better flow). Setup=av7 w/ 74cc airsal, 16 dellorto sha, with stock variator, 11-54 gearing. You really need to lower the weights for this DUH bc it wont kick in till 20~ but I slapped a launch bar on it and that lets me zip off a bit quicker on the hills. If you aren't going to fuck with your variator then get that lil mini turbo pipe w/o the mini muffler bc itll give ya sweet ass take off compared to this damn pipe (the one with the mini muffler will end up being chopped off anyways due to pedal) but kiss your kickstand goodbye with the mini turbo (but fuck if that pipe wasnt perfect for all around)
