Hi, can I put a Big Gun exhaust on the outlander 570 without a power box. The Outlander is 2019 and has an O2 sensor. Some say it will be a poor fuel mixture, while others say they can put it without a power box. Who has experience let me help...

I think t will need to be tuned. One way to find out. Install the Big Gun and run it.

The O2 sensor on your bike, is the "tuner", in very dumbed-down language.

The lack of emissions feedback on the majority of the BRP lineup, is why tuners are so highly recommended, when changing exhaust. Your bike/ECM has the capability to adjust the fuel map in response to you changing the exhaust out.

Whether or not it's got enough adjustability to not affect drivability, I guess remains to be seen.
