JBA Performance Exhaust Systems :: Available Now! Magnum/Charger/300C 5.7L 2.5" JBA Exhaust System Magnum/Charger/300C 6.1L (SRT8) 3" JBA Exhaust System 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. ::Exhaust Features:: • Aggressive sound without annoying interior resonance • Smooth flowing mandrel-bent tubing • Stainless steel construction • High flow JBA mufflers • Polished stainless steel chrome plated rolled lip exhaust tip with JBA logo • Easy bolt-on installation • High quality hardware • O.E. style exhaust hangers • Will not void factory warranty • 50 state smog legal* *For most applications
