Description
The AWE 0FG Exhaust Suite for the GMT T1XX Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, and GMC Yukon XL 5.3L is designed to deliver a deeper, richer V8 exhaust note while improving exhaust flow and maintaining factory-style drivability.
Built around a 3-inch cat-back configuration, the 0FG system is engineered specifically for the 5.3L V8 and is available for both standard- and long-wheelbase models. AWE developed the system with cylinder deactivation functions in mind, helping maintain a refined exhaust character across different driving conditions.
The exhaust combines a tailored mid-muffler and resonator configuration with a clean, straight-through design to deliver a deep, rich tone without unnecessary restriction. The result is a performance-focused exhaust system designed to provide full-size sound while maintaining a refined driving experience.
The 0FG also offers multiple exhaust tip configurations to accommodate different factory bumper styles, including dual and quad outlet designs.

Exhaust Sound & Acoustics
The AWE 0FG exhaust is designed around the characteristics of the 5.3L V8, combining a free-flowing exhaust layout with a specifically tuned mid-muffler and resonator combination.
Rather than simply increasing exhaust volume, AWE designed the system to produce a deep and rich V8 tone while maintaining a refined sound during normal driving.
The system's cylinder-deactivation-focused tuning helps manage the changes in exhaust character associated with the engine's operating modes.
Exhaust Tip Options
The 0FG Exhaust Suite provides multiple tip configurations to match different rear bumper designs.
For flat bumper applications, the system offers dual 4.5-inch double-walled, slash-cut tips in either Chrome Silver or Diamond Black.
For bumpers equipped with exhaust cutouts, the system offers quad 4.5-inch double-walled, slash-cut tips in Chrome Silver or Diamond Black.
The quad outlet configuration uses ball-and-socket joints to allow precise adjustment and alignment with the factory bumper cutouts.
Construction & Design
AWE uses a clean, straight-through exhaust design intended to maximize exhaust flow while maintaining the desired sound characteristics.
The front pipe incorporates an internally lined stainless steel flex section, providing additional rigidity in a critical area of the exhaust system.
The system is engineered as a complete bolt-on solution, eliminating the need for cutting during installation.
Installation
The AWE 0FG Exhaust Suite is designed for bolt-on installation with no cutting required.
Model-specific components are supplied according to the selected vehicle and wheelbase configuration. The ball-and-socket connections on quad-tip configurations allow the exhaust outlets to be accurately positioned within the factory bumper cutouts.
Professional installation is recommended to ensure proper exhaust alignment and clearance.
