Critical Fitment Notes

- Four-wheel-drive applications may require trimming or modifying the pipes for clearance.
- Vehicles with the larger 4L80E transmission may require trimming the bellhousing ears for clearance.
- Some early 2500-series chassis may have fitment conflicts because of earlier frame designs.
- Confirm engine code, platform, chassis, drivetrain, transmission, steering, suspension, transfer case, oxygen-sensor locations, and exhaust connection dimensions before ordering.
Important Notes
- Raw stainless finish; not polished.
- Professional installation is recommended. Cutting, welding, wiring extensions, tuning, and additional exhaust hardware may be required.
- Verify emissions and road-use legality before purchase and installation.
