Hey guys, first off i wanna say I’m really new to this and new to the atv, i just recently purchased a 09 kfx450r monster edition and it’s completely stock. I wanted to get a full yoshimura exhaust but I’ve heard here and there that you would have to tune it with a power commander in order for it to work because you would run either rich or to lean when you put a new exhaust on due to the airflow increase or how ever it was said. KFX450R 08-14 RS-2 Stainless Full Exhaust, w/ Aluminum Muffler
That’s the link to the one i wanna get and I’m not sure if i would have to tune it because on the website it doesn’t say, and I’ve looked all over forums and haven’t really found an answer to my question, and if i had to tune it how would i exactly?
