Note on Vehicle Configuration

This listing includes the term "driver" or "passenger". Please note that this may refer to a region specific variation based on vehicle configuration (LHD/RHD) or regional preferences. Much of our database relates to US sourced products where "Driver" typically refers to the left-hand side in LHD vehicles, and "passenger" to the right. In RHD vehicles, this terminology is reversed. Review product details carefully for compatibility. Contact support if you have any questions. StreetFX may not accept returns for special order products.

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.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.
