Installation Notes and Tips

Confirm the vehicle’s year, engine/emissions configuration, and exhaust layout before ordering. Fitment includes notes for premium models, California or Federal emission systems on certain applications, and some vehicles built before 10/16/2006. If the exhaust uses a welded assembly, replace all required related parts during service to ensure proper alignment and sealing. Verify the 3-inch inlet and 2.75-inch outlet dimensions against the existing exhaust system before installation.
