Description
The Apollo GT Series 3-Inch 409 Stainless Steel Cat-Back Exhaust System with Polished Tips is designed to deliver proven performance gains, aggressive exhaust tone, and long-lasting durability for select Chevrolet Silverado 1500 and GMC Sierra 1500 applications. Engineered for enthusiasts seeking enhanced sound and performance, this system offers an OEM-quality fit with a bold visual upgrade.
This cat-back exhaust system is constructed from 3-inch mandrel-bent 409 stainless steel tubing, providing excellent strength, heat resistance, and corrosion protection. Smooth mandrel bends reduce restriction and turbulence, improving exhaust flow 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 deliver a strong, aggressive exhaust note that enhances performance without sacrificing drivability.
The system is finished with dual 4.5-inch diameter polished 304 stainless steel clamp-on exhaust tips, each featuring a riveted aFe POWER logo plate for a refined yet aggressive appearance.
Installation is straightforward and fully bolt-on, utilizing factory-style hangers to ensure a secure and precise fit. All necessary hardware is included, and no cutting or modifications are required for a hassle-free installation.
Designed using advanced computer-aided design (CAD) technology, this exhaust system provides 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 premium craftsmanship, aggressive sound, and reliable performance.
