Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
