Not my cuppa Starbucks, but what the hey. Bet that bike has better cornering ability in righthand turns
I've seen all manner of non-stock exhausts used on CT70s (ST70 Daxes, actually). Usually it just requires a custom hanger. Two caveats: the low-mount type will interfere with the buddy pegs and most all are lacking in the area of heat shielding. That won't set the bike ablaze, but either someone's leg can get slow-roasted or you'll end up burning a hand/arm while working on the bike at some point
