Always interested in others’ performance mods👍🏻Honestly, I suggest you don't take the time and expense to take the CAT off. It actually doesn't slow down the air flow much. To me, the big advantage is the weight reduction but this weight is down low where it doesn't matter as much. You can drop 5 lbs up high if you just replace the stock lead battery with a Shorai lithium battery (and charger). If you're interested, I can list the performance mods I've made to my 750.
