DPF-Back Exhaust

This system is constructed out of large 4" diameter tubing that is mandrel-bent for maximum air flow, corrosion resistance, and strength. It eliminates the factory muffler, providing smooth sounding performance. This Large Bore-HD DPF-Back exhaust system utilizes factory mounting locations and OE style bayonet hangers, providing stability and a hassle-free installation. This system includes a polished intercooled clamp-on tip designed to reduce exhaust gas temperatures at the tailpipe.

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.
