I have 1/2" relo kit and full TTI exhaust system, not a single problem anywhere. My tailpipes are new as of a few months ago. How old are yours? I wonder if they changed designs. It think it probably also depends on the type of leaf springs you have. If mine were flatter, I can see how it would be a problem. That's over an inch of clearance. The other side is nearly identical to this one. Oh, and these are 2.5" pipes.
