Straightline Performance Terminal Bypass Elimination Plug
This Straightline Performance Terminal Bypass Elimination Plug (145-112) replaces the factory exhaust pipe sensor on many Polaris and Arctic Cat snowmobiles, so the machine runs consistently without relying on a sensor that can fail or send inaccurate readings. It installs quickly in place of the factory sensor connector and lets you remove the sensor from the exhaust system entirely if you choose.
Built for riders who want to cut a potential failure point out of their exhaust, it suits backcountry riding and performance setups alike, and it fits 2018 and newer Polaris 650, 800, 850, 900R and Boost mufflers as well as all Arctic Cat models from 2011 onward on both muffler and single pipe.
