Also, I cannot really tell from the pics, but it would be good to know if the bolt holding the pipe to the frame is isolated with a bushing or grommet to reduce vibrations to the cabin.
I can't really tell the from the pics, but are they not using the same bolt location as the stock side pipes? Because the stock bolt location already has a rubber isolator.
