I have a 02 Road King Classic and I installed the SE performance pipes with the endcaps that you can change out. I installed the billet end caps, but the exhaust seems stronger on the right side than the left side. When I put my hand behind the pipes I can feel, and hear a stonger pressure from the right side on the pipe than the left. Any answers on this problem? Also, I have noticed that with the EFI engine that the idle RPM is a little higher than the carb models. Is that normal with the EFI engines? I just need some help, it's my first harley davidson.
