waggs:
You have other choices. You can have the tailpipes adjusted by a good exhaust shop. But, easier and at no cost to you is adjusting the tailpipes. First, you can adjust the tailpipes length-wise by loosening the clamps at the mufflers and pulling the pipes out a little bit. You don't need much for clearance. Secondly, there is clearance to be had by turning the tailpipes clockwise or counter-clockwise.
HTH,
