Hey guys I got a 2bros slip on and am planning to get the K&N air filter. Should i rejet or should I be okay since the 2bros is just a slip on? does anyone have this combination without rejetting?

You could prolly get away with just shimming. Personally I'd rejet...

You should re-jet after just the slip on. Adding a K&N it's a must. You're bike won't have enough fuel to pull beyond 10k.
