From the H-pipe rearward, the 2-1/2-inch exhaust consists of DynoMax's Ultra Flo welded mufflers and brushed stainless steel tips. The tailpipes kept wanting to press up against the rear bumper cover, and we thought we might have to modify the existing hangers. We realized, however, that the mufflers needed to be pushed up into the chassis as far as they would go while leaving at least 1/2 inch of space. This angled the tailpipes to where they needed to be. Note that the Ford Racing Performance Parts aluminum driveshaft from Texas Mustang Parts has been installed as well.
