The right side long pipe is a little lower than the left, however it went on like stock ones I installed at the dealership, which were lower on the right as well. Gardner has a Original SD system sitting in their shop. Although you could have a bend issue during building, mine and 2 others I have done are fine. Power ? There is 320 ish stock HP in my motor ,and these pipes don't affect low end torque much. At least I am well beyond the "Dronemaster" Days.. LOL
