The aFe Apollo GT Series 4-inch cat-back exhaust system is designed to enhance the performance and sound of your GM Silverado or Sierra 1500 pickup trucks from 2014 to 2016 equipped with a V8 6.2L engine. Constructed from durable 409 stainless steel, this system features mandrel-bent tubing that ensures maximum strength and optimal exhaust flow. The high-flow muffler is engineered to produce a deep, aggressive exhaust note while maintaining reliability under demanding conditions. A polished 5-inch diameter intercooled exhaust tip, riveted with the aFe POWER logo plate, provides a stylish finishing touch that complements the rugged look of your truck.
The system is a straightforward bolt-on installation utilizing factory-style hangers, eliminating the need for cutting or modifications. It incorporates a heavy-duty flex pipe with an internal interlock liner, which adds to the durability and longevity of the exhaust system. Advanced computer-aided design (CAD) technology ensures precise fitment for high tolerance and seamless integration with your vehicle*s factory components. Each component is 100% MIG-welded for race-proven strength, ensuring durability and consistent performance.
Designed specifically for Crew Cab/Short Bed, Crew Cab/Long Bed, and Extended Cab/Long Bed configurations, this exhaust system fits trucks with wheelbases ranging from 143.5 to 153 inches. It does not require a CARB EO#, making it suitable for various regions. Manufactured in Corona, California, the aFe Apollo GT Series offers a combination of high-quality materials, advanced engineering, and a bold aesthetic, making it an ideal upgrade for enthusiasts seeking improved exhaust sound, enhanced performance, and a durable, stylish finish for their trucks.
