I just picked up an 04 Road Glide, TC88, 3,000 miles on it, with ThunderHeaders 2 into 1. The P.O. never upgraded the air filter or added a Power Commander. I intend to do both but wonder if I am okay if I do not do it right away and just ride with the pipes. My philosophy has always been that you can only exhaust what you put in, so if the intake is not opened, the pipes may flow a little more but not enough to cause the engine to run too lean. BTW, the pipes have only been on the bike for about 2,000 miles. Any opinions? Waiting is okay or upgrade ASAP?
