I have the American Thunder catback, and 315 tires resting on 17x10.5" rims. No rubbing anywhere on anything.

Had it happen on other Mustangs. Mark with Sharpie, take pipe off, tap with hammer until it doesn't rub anymore.

More of an issue with stock UCA's thank with the Mega Bite UCA's I've used with that catback.
