When I got my XJR towed on the flatbed . The muffler/exhaust tips always scrape the ground.

My car is wearing 19 inch Montreal and one spec tire and stock springs.

Whenever I hear the scraping sound. My heart is just bleeding. BTW, i got the powerhouse UK straight pipe end exhaust.

 

I've had mine flat bedded and it didn't scrape and I'm running 18 Pentas and mines a VDP. I would hope the driver would have minimized the ramp incline to prevent that. Your tips shouldn't be more than 1" from the bumper exit and a little less than flush with the outer most point of the bumper....any farther and that's on you.
