Available Exhaust Variants
This off-road race exhaust system is available in two configurations to match your performance goals:
1) 5-Inch Turbo-Back Exhaust System
- Replaces the factory exhaust from the turbocharger back

Performance Benefit: Maximizes airflow directly from the turbo outlet, helping improve throttle response, exhaust gas temperatures (EGTs), and overall engine efficiency.
2) 4-Inch Downpipe-Back Exhaust System
- Connects to the factory or aftermarket downpipe
- 4" diameter piping from the downpipe to the tail section
- Removes restrictive emissions components (race/off-road use only)
- Balanced option for improved flow without full turbo-back replacement
Performance Benefit: Improves exhaust flow and reduces restriction compared to stock, supporting better engine breathing and performance gains.
Features of Cummins 6.7L Exhaust:
- No Bungs: This design removes bungs to ensure maximum airflow.
- Stainless Steel Tubing: High-quality stainless steel construction provides durability and resists corrosion.
- Mandrel Bent Tubing: Guarantees smooth airflow, leading to better performance.
