A cat-back exhaust replaces the factory pipes, muffler and tips behind the catalytic converter. This is aFe's Vulcan Series system, built from 3-inch stainless tubing with polished tips.
why this one — aFe claims the smallest gain of any cat-back here, +5 hp and +6 lb-ft, so at $1,153 you are paying mostly for sound and stainless construction. One ordering trap: aFe also sells an older MACH Force-Xp cat-back that fits the 2019 Silverado 1500 LD carryover body, which is a different truck, so buy by this Vulcan part number. A black-tip version of the same system exists if polished is not your look.
CLAIMED - aFe's own spec language ("Dyno-Proven Gains up to +5 HP & +6 Lbs. x Ft. TQ") appears on the Phastek Performance listing mirroring aFe manufacturer copy; direct afepower.com fetch confirmed part number/name but full spec table did not render.
