2014–2018 Chevrolet Silverado 1500 & GMC Sierra 1500 6.2L V8
The aFe POWER Apollo GT Series 4" Cat-Back Exhaust System is engineered to deliver increased exhaust flow, a deep aggressive exhaust tone, and long-lasting durability for 2014–2018 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with the 6.2L V8 engine.

4" Mandrel-Bent 409 Stainless Steel Construction
This exhaust system is constructed from 4-inch mandrel-bent 409 stainless steel tubing, maximizing exhaust flow while reducing backpressure and turbulence. Mandrel bending maintains a consistent internal diameter throughout the system, improving throttle response, horsepower, and torque while ensuring excellent corrosion resistance and durability in harsh driving conditions.
High-Flow 409 Stainless Steel Muffler
The Apollo GT exhaust features a high-flow 409 stainless steel muffler designed to enhance exhaust velocity while producing a deep, aggressive tone without excessive drone. This tuned muffler improves performance across the power band while maintaining refined sound quality for daily driving or towing.
5" Black Intercooled Stainless Steel Exhaust Tip
Finishing the system is a 5-inch diameter black 409 stainless steel intercooled clamp-on exhaust tip, adding a bold, aggressive look. The tip features a riveted aFe POWER logo plate, delivering premium styling that complements the performance-focused design.
Heavy-Duty Interlock Flex Pipe
A reinforced flex pipe with an internal interlock liner is integrated into the system to absorb vibration, reduce stress on exhaust components, and improve long-term durability—especially under high-load and high-heat conditions.
Precision Fit & Hassle-Free Installation
Designed using state-of-the-art computer-aided design (CAD), this cat-back exhaust delivers precise factory-style fitment. OE-style hangers ensure proper alignment and stability, while the 100% MIG-welded construction provides superior strength and reliability.
