In the world of muscle cars, 4 doors is usually a deal killer. Don't tell that to the guys at Dodge and Chrysler. They've taken the powerful new HEMI and dropped it in their new LX platform chassis complete with 4 doors and a roomy interior. The result is a fresh new muscle car look for the street with good ol' fashion American V8 power under the hood. But just like the early days of hot rodding - there is more power to be had with the right combination. JBA has designed the ultimate solution with performance smog legal headers and exhaust systems designed for maximum power. How does +24 hp and +32 lb-ft of torque sound? JBA's engineers tested and tuned these systems for the perfect balance of power and sound. There is even a 3"system developed specifically for the SRT8 models.

JBA has been building and testing headers for the 5.7L HEMI since it was introduced in 2003. With this experience our engineers were familiar with the design and flow characteristic of the heads and knew what the engine would respond best to. The engineering team at JBA addressed the critical short comings of the 5.7L HEMI exhaust manifolds with a fresh design that started with high flowing 1-3/4" mandrel bent stainless steel tubing. By giving each cylinder a smooth unrestricted path, back pressure is reduced and flow goes way up. The giant 3" collector was engineered using JBA's patented Firecone® - a unique directional device similar to what you find on a long tube race header - which improves flow by providing efficient scavenging of exhaust gasses. Other standard features like thick 3/8" CNC laser-cut flanges, O.E. style JBA sealing dome connection to the exhaust and high quality hardware make them a highly effective upgrade for the HEMI. Bolt-on a set and feel the JBA difference.

If you're looking to get even more power from your 5.7L HEMI powered Magnum, Charger or 300C, check out these new high flow Mid-pipes from JBA. These precision built components are engineered to deliver a huge increase in performance for the re-born legend and a powerful exhaust note. These new mid-pipes feature mandrel-bent stainless steel tubing, high flow catalytic converters, and provisions for 02 sensors for an easy bolt-on installation. Once installed, these components open up the exhaust system for substantial performance gains and a healthy change in the exhaust note. Installation can be done in about one hour with common tools. These mid-pipes are designed to work in conjunction with JBA Cat4ward® headers or factory manifolds. Note: Does not fit AWD Models.

Magnum/Charger SRT8 3" JBA Exhaust System
Part No. 40-1601 Click to enlarge

Nothing says "power" like a great sounding exhaust system. The new LX cars are quick but the stock exhaust keeps the HEMI from making maximum power and is far too mellow. JBA spent countless hours testing and tuning to engineer the perfect exhaust for the Magnum and Charger including SRT8 models. The end result is an ultra high flow system that makes real power with the authentic sound of a true muscle car without annoying interior resonance common on other systems. Each JBA exhaust features smooth flowing mandrel-bent tubing, high quality hardware, fully welded JBA mufflers and finish with great looking polished and chrome plated stainless steel rolled lip tips. Dyno test show gains of +10 hp and +18 lb-ft of torque on the 5.7 L and 17.1hp and 21.9 lb-ft of torque on the SRT8 at 4000 RPM. Not only do these systems sound awesome but they look great too. Don't settle for excessive noise and cheap tips that turn yellow. JBA has the power, sound and quality you're looking for. Available Now!
