JBA Long Tubes not only improve the power and sound of the Challenger, it helps the engine run more efficiently as well, leading to better gas mileage and fuel efficiency. JBA has already developed successful 1 3/4 Smog Legal Shorties for the LX Charger and 300C which when combined with the exhaust system led to dyno'd gains of 24 horsepower and 32 ft/lbs of torque to the wheels. Given JBA's pedigree for more power, better sound, and higher quality, our excellent research and development team is currently calcuating and machining longtube headers that will most definitely get the most out the Challenger both in power and efficiency. With its patented Firecone collector technology and a limited lifetime warranty and the finest materials available such as stainless steel and 3/8" flanges, the JBA Longtube Race header is unlike any other in the industry.
