AFE's Gemini XV Dual Exhaust System features an electronically controlled exhaust cutout valve so you can quickly switch between mild and aggressive tones with just a push of a button. Close the cutoff when driving through a residential area to stay low key. Then open it up to let your Sierra howl while cruising down the highway.
High Quality Construction. AFE proudly manufactures their Gemini XV Series Exhaust Systems from high quality T-304 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.
