Answer QuestionWhile it's not required, if you want to get the best possible performance out of your XL1200X Forty-Eight, you should certainly modify fueling to suit. In this way, you're guaranteed to get the most out of this Cobra Speedster Short RPT for the Sportster 48 - or any other exhaust system modification, for that matter. We recommend the Cobra Fi2000 PowrPro Black Fuel Controller for the Sportster as it's a great match for the Cobra Speedster exhaust system.
