Hey everyone, I just finished putting the exhaust on my ol ladies 07 rancher 420 and when I fired it up to test it everything went fine until I have it some throttle, when I push the throttle in really slow it runs/sounds fine, but when I push the throttle in fast it sounds like it’s bogging down and almost stalling before it revs up, if anyone has any ideas on what it could be please let me know.
