I am no expert but I think you will be fine as long as you check your plug....all you will do is allow the exhaust to exit slightly faster, a slip on actually does very little than make it sound better, you have not changed your fuel/air mixture by adding a slip on as you would if you were to add a intake kit and no controller that is where you will run into problems...although it is best to have the controller..... just my .02
