The MagnaFlow 19693 Black Series Filter-Back Performance Exhaust System replaces the restrictive factory exhaust after the DPF on 2024–2025 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD trucks with the 6.6L Duramax diesel, delivering dyno-proven gains of 10–15 rear-wheel horsepower and 20–30 lb-ft of torque through mandrel-bent 4-inch stainless tubing that reduces backpressure and improves turbo spool for quicker acceleration and better throttle response.
Featuring a straight-through perforated core muffler, 6-inch black stainless tips with intercooled design to prevent heat buildup, and heavy-duty band clamps for secure fitment, this system maintains emissions compliance while enhancing towing performance up to 18,500 lbs and fuel efficiency. The black powder-coated finish resists corrosion and high temperatures for long-lasting durability in harsh diesel environments.
For HD truck owners who demand aggressive diesel sound with refined cabin manners, the 19693 Black Series system provides the complete filter-back upgrade for work-site dominance and highway confidence.
