TB Monkey 125 Performance Exhaust 1 – Stainless
Our new Monkey 125 Performance Exhaust (2021 and older models only) was developed for performance, looks, and value. We felt an alternative was needed to the massive size of the stock and most aftermarket exhausts. We based this exhaust on our popular Z50 (the original “Monkey”) aftermarket performance exhausts that we have been selling for nearly 20 years. They increase performance while providing a clean and compact look that better fits the small Monkey in our opinion. It will fit perfectly, sound great, and improve the performance of your Monkey at a reasonable price for a quality exhaust. The key features are:
- Stainless Can
- Chromed Stepped-up Header
- Chromed Guard
- Does not require ECU flashing/tuning (but doing so would add additional performance)
- Gains 1hp and .59 torque*
- Weighs 4.2lbs (stock is 11lbs)
- Includes a removable silencer
- Works great with stock engines or ones with big bore kits
*Dyno runs were done for us by a local shop (McNew’s Cycle Tuning, Dillsburg PA). The first one pictured was done on a brand new (unmodified engine) Monkey. The second one was done with the new exhaust with the silencer inserted and the third one without the silencer. No ECU flashing/tuning was done or needed (but would add more performance if done). If using with other performance products like cams or big bore kits, ECU flashing/tuning will be needed.
