The aFe MACHForce XP cat-back for GM Silverado/Sierra 1500 (2009–2018 and select 2019 models) uses 3in mandrel-bent stainless steel tubing, TIG welds and high-flow mufflers plus an X-pipe to balance pulses and optimize flow. It keeps factory hanger locations for a bolt-in installation, finishes with polished quad tips, and is manufactured in Corona, California to a tuned tube-length design that aims to improve flow and deliver an aggressive exhaust note.
