I called Borla last week and spoke to someone in thier tech department. I was told that their split rear would not interfere with the spare tire. I specificaly asked about the 18" spare and was told there would be no problems at all. Everything is bolt on and you should not have to make any mods to put the pipe on.

The Borla split rear part number is 140087.

 

That is what I would like with the exeption of having it on both sides of the tires. Do they make one?
