Description
Aggressive Sound and Power. Wake up the sound of your 4.3L Sierra with an AFE Apollo GT Series 3-inch Dual Exhaust System. By replacing the factory exhaust with a Apollo GT Series Exhaust you will add an aggressive exhaust note to your 4.3L powered Sierra, without any drone. This Apollo GT Series Exhaust won't only improve the sound of your Sierra, but it will also improve its power as well. By eliminating the restrictive stock muffler and piping, you will increase exhaust flow for a noticeable increase in both power and performance.
High Quality Construction. AFE proudly manufactures their Apollo GT Series Exhaust Systems from high quality T-409 stainless steel tubing for superior strength and enduring corrosion resistance. Featuring ultra smooth mandrel bent 3-inch diameter piping and a high flow muffler, this AFE Cat-Back will significantly out flow your truck's original factory exhaust system. This system also includes a pair of 5-inch polished stainless steel exhaust tips with an aFe POWER logo plate for impressive good looks.
Direct Bolt-On Installation. This AFE Cat-Back Exhaust was engineered to be a direct bolt-on upgrade replacement. This Cat-Back Exhaust System will easily bolt straight up to the factory piping without any cutting, modifications or special tools required for an easy straight forward installation that can be completed in about two to three hours.
Application. This AFE Apollo GT Series 3-Inch Dual Exhaust System with Polished Tips; Rear Exit is designed to fit 2009-2018 4.3L GMC Sierra 1500 Regular Cab models with a Long Box.
