Hey Willie, new to this forum, maybe you can answer a question for me. After owning a 2013 sportster 48 for a year and researching exhaust and air intake mods, I finally went with the DIY cheap mod. Drilled out stock muffler baffle with 1" hole bit, swapped to K&N air filter using my stock cover with out the airflow restrictor plastic thing. No back fire , no chirping, no lose of power, sounds good, runs better. Is there a down side to what I've done. Should I invest in a Fuel Injector computer like a Cobra FI2000. Your posts sound like you know your ****, any opinion is appreciated, thanks in advance.
