I have my tips set low as well; aesthetically it seems to work with the diagonal cut tips. It's on a first generation euro bumper cover though. Recall that the first generation PSE had bypass pipes in the region of your second generation bumper cover "diffuser vents". IIRC the second gen PSE did not have the bypass pipes and the bumper cover did not allow for them. Please correct me if I am wrong. So you will naturally have proximity isssues that will have to be adjusted for.
That said I have I rubbing issues with the muffler going in and out over the years as pictured. It is the nature of the beast.
The sound of the Fister cannot be beat so it's worth it.
