Enhanced Flow and Style Upgrade. The PPE Performance DPF-Back Single Exhaust System with Raw Tubing and Polished Tip is built to boost your 2023 to 2026 3.0L Duramax Sierra 1500's exhaust flow and visual appeal. This system replaces the factory muffler with a free-flowing design, improving throttle response and delivering a more aggressive tone while maintaining emissions compliance by retaining the DPF.

Construction and Appearance. Constructed from high-grade 4-inch 304 stainless steel, this exhaust system resists corrosion and high-temperature fatigue. The raw tubing is complemented by a polished chrome tip for a clean, performance-driven look. Designed with a single side exit, it enhances rear-end styling while preserving factory functionality by reusing stock mounting points and exhaust valve locations.

Installation. Installation is easy for experienced DIYers or professionals but requires cutting of the stock exhaust for proper fitment. The system is a direct replacement for GM part numbers 84495633 and 84495632 and includes all necessary hardware for a secure install.

Warranty. The PPE Performance DPF-Back Exhaust System includes a one-year limited warranty.

Application. This PPE Performance DPF-Back Single Exhaust System with Raw Tubing and Polished Tip fits 2023 to 2026 GMC Sierra 1500 models equipped with the 3.0L Duramax diesel engine.
