Frequently Asked Questions About Ford F650-F750 Truck DPF & Mufflers

What years of Ford F650-F750 trucks do these DPF systems and mufflers fit?

Our DPF systems and mufflers are designed for Ford F650-F750 trucks from 2008 to present, which covers all models equipped with diesel particulate filter requirements. The 2008-2010 models use a different mounting configuration than 2011+ models, so be sure to select the correct year range when ordering. Most universal mufflers will fit all years, but DPF-specific components must match your truck's exact year and engine configuration.

How difficult is it to install a replacement DPF or muffler on my F650-F750?

Installation typically takes 2-4 hours for an experienced technician. The main challenges include the weight of the components (DPF units can weigh 40-60 pounds) and accessing the mounting points on lifted trucks. You'll need standard exhaust tools, including pipe cutters, clamps, and hangers. Many customers report that having a second person helps significantly with alignment. Professional installation is recommended for DPF replacements to ensure proper sensor connections and system calibration.

What's the difference between OEM and aftermarket DPF filters for these trucks?

OEM DPF filters typically last 100,000-150,000 miles and come with Ford's warranty coverage. Aftermarket options from reputable manufacturers like Redline and Skyline offer comparable performance at 30-40% less cost. The main differences are in the substrate material (cordierite vs. silicon carbide) and cell density. Aftermarket units may require more frequent cleaning intervals but provide adequate filtration for most commercial applications. Always verify that aftermarket DPFs meet EPA compliance standards.

Can I replace just the muffler without changing the entire exhaust system?

Yes, most F650-F750 mufflers can be replaced independently using the existing exhaust piping. Standard muffler sizes for these trucks are 5-inch inlet/outlet diameter with lengths ranging from 31 to 44 inches. Measure your current muffler's dimensions and mounting style (center/center, offset/center, or center/offset) before ordering. Keep in mind that replacing just the muffler won't address DPF issues if you're experiencing regeneration problems or check engine lights.

How often should I clean or service the DPF on my F650-F750?

Under normal operating conditions, DPF cleaning is recommended every 150,000-200,000 miles or when the differential pressure sensor indicates excessive buildup. Trucks used for frequent short trips or excessive idling may need cleaning as often as every 75,000 miles. Warning signs include frequent regeneration cycles, reduced fuel economy, and dashboard warning lights. Professional DPF cleaning services typically cost $300-500 and can extend the filter's life significantly compared to replacement costs of $2,000-4,000.
