What you’re looking for "Put it on my 2014 z400 a couple years ago also used the hmf tuner for fuel injection it gave it a noticeable jump in power there is more low to mid range torque helping the acceleration and it sounds awesome.

Big Gun Evo Race Slip-On Exhaust Big Gun Evo Race Slip-On Exhaust Yfz128 Awesome! "I bought this exhaust for my YFZ450, and I absolutely love it! Be aware though, it is insanely loud. If you want to go to the track with it, you will need a quiet core. It DEFINITELY increases horsepower, and just wakes YFZ's up. Overall a amazing product."
