A new exhaust from MNNTHBX, I quote: A MNNTHBX EXCLUSIVE! We've partnered with Yoshimura to bring a top system to the GY6 game. PERFECT fitment. Works finish header. Welded on bung. Includes db killer. Tapered header design for optimum performance. Fatty friendly. Gone are the days of paying inflated prices for somebody's cousin to weld up a Yosh pipe in the garage. This is the only place to get a genuine Yoshimura built GY6 exhaust. This unit exudes quality, and just happens to be priced better than the pretenders. Win.

Any thoughts of this being 100% easy fit on a stock Zoomer (FI)?
Compared with a stock exhaust:
Since I'm looking for an aftermarket exhaust for my Zoomer and I have fuel injection I wanna keep my O2 sensor, but I don't find many exhaust with a O2 sensor thread, so this exhaust could be the one since has an O2 thread.
