My rineharts came with a spacer for the right floorboard. It's needed to move the floorboard out. Otherwise it may rub. I already had spacers on mine and after install I can see why they are needed.
I had rush 2.0 pipes first and the chrome was crap. They burned out orig. packing after 5k and they sound like empty cans. No way can they be compared to Rinehart.
