Description
The Apollo GT Series 3-Inch 409 Stainless Steel Cat-Back Exhaust System with Black Tips is engineered to deliver proven performance gains, aggressive sound, and long-lasting durability for select Chevrolet Silverado 1500 and GMC Sierra 1500 applications. Designed for performance-driven truck owners, this system enhances exhaust flow while maintaining precise, OEM-style fitment.
Constructed from 3-inch mandrel-bent 409 stainless steel tubing, this exhaust system provides excellent heat resistance and durability under demanding conditions. Smooth mandrel bends reduce exhaust restriction and turbulence, improving airflow and contributing to dyno-proven gains of up to +14 horsepower and +17 lb-ft of torque, as measured on aFe POWER’s in-house dynamometer.
At the core of the Apollo GT system is a high-flow stainless steel muffler, tuned to produce a bold, aggressive exhaust tone while minimizing unwanted restriction. The sound profile delivers a powerful presence under throttle without sacrificing drivability.
The system is finished with dual 4.5-inch diameter black 304 stainless steel clamp-on exhaust tips, each featuring a riveted aFe POWER logo plate for a distinctive and aggressive appearance.
Installation is completely bolt-on, utilizing factory-style hangers for a secure and precise fit. All necessary hardware is included, and no cutting or modifications are required, ensuring a hassle-free installation.
Engineered using advanced computer-aided design (CAD) technology, this exhaust system is designed for high-tolerance factory fitment. Every system is 100% MIG-welded for race-proven strength and long-term durability.
Proudly engineered and manufactured in Corona, California, aFe POWER exhaust systems deliver uncompromising quality, performance, and sound.
