I've had no issues with the Pacesetter long tubes and ground clearance. Even after adding cats do the off-road ypipe, I still have not dragged any part of the exhaust on the pavement and that is good considering my driveway is at a pretty steep incline. I think it also helps that the Pacesetters are a slip-fit style header eliminating the bulky flange connections.

 

from what i understand is that shorty headers will bolt up to the stock cats. if i were to get shorty headers and get my exhaust redone from the headers back with no cats, would that equal to LT's?
