MagnaFlow Exhaust Products 19840 - Cat-Back Exhaust Systems

Description

The MagnaFlow SPEQ Series #19840 cat-back exhaust system is engineered as the ultimate performance upgrade for the Dodge Charger powered by the new twin-turbo L6 3.0L Sixpack. Designed to amplify modern muscle sound, flow, and power, this dyno proven system combines precision manufacturing with an aggressive sound profile. It is constructed from high-flow 3” mandrel-bent premium 304 stainless steel tubing for exceptional corrosion resistance and long-term structural integrity. Connections are secured using race-bred V-band clamps, providing a leak-free assembly that remains stable across heat cycles. Exhaust flow is optimized through a Tru-X crossover x-pipe that enhances pulse scavenging and smooths transitions. This feeds into mid-body straight pipe deletes and a pair of straight-through mufflers engineered specifically for the high-output Sixpack engine. The result is a deep, assertive tone that comes alive under throttle while preserving a drone-free cabin experience at cruising speeds. The system exits through dual split 4.5” black chrome tips etched with the MagnaFlow logo, delivering a striking appearance that matches the system’s performance-focused attitude. Fitment is precise due to 3D scanning and CNC robotic manufacturing, ensuring a direct-fit installation that replaces all factory components behind the catalytic converters. Reinforced hangers provide solid attachment to OEM mounting points, maintaining secure alignment and stability. Full factory valve functionality is retained by MagnaFlow’s cast stainless performance valves, allowing full integration with the Charger’s active sound management and drive modes. Backed by MagnaFlow’s limited lifetime construction warranty, this cat-back delivers a measurable upgrade in sound quality, flow efficiency, and overall power. Designed with a focus on real-world performance, it enhances the twin-turbo Charger with a power-focused exhaust tone and the premium construction demanded by modern high-output muscle.

⭐️⭐️⭐️⭐️⭐️ WOW – That’s How You Stand Behind Your Work H&H installed my airbags last year, and recently I ran into an issue where they stopped working. From the very first call, they were incredibly helpful and patient, walking me through troubleshooting over the phone trying to save me a trip. When we couldn’t get it resolved, I called first thing Monday morning and they had me scheduled right away. They got the truck in, diagnosed the issue, and replaced the parts — completely under warranty — no hassle, no excuses. A couple hours later I was back on the road. That’s rare service these days. Professional. Honest. Stand-up guys who truly stand behind their work. H&H is hands down the place to go for all your truck needs. 💪
