Hey guys, I am looking for an exhaust for my new 2018 XP1K. I’d like something that has a little more bark, however, I don’t want to hear an awful drone while riding. I do rock crawling/trail riding so I really don’t care about performance improvements. Do all aftermarket exhausts require a new fuel controller or custom ECU tune? Also, if the exhaust does not come with a hole for the O2 sensor, will it throw a code? Any input is appreciated guys. Thanks
