Stainless Works 3" H-pipe catback for 2015–2016 Mustang GT (5.0L) uses retro chambered mufflers with full 3" cores and mirror-polished stainless slash-cut conical double-wall tips. The kit includes hangers and clamps and is meant to mate to Stainless Works Performance Connect headers so the system maintains a continuous 3" diameter for improved flow and a bolt-on installation.
