High performance kit with stainless steel headers and RACING DYNAMICS Eprom software, 6 cylinder, 3 series E36 325/328/M3 M50, M50TU motors. Equal length pipes, as used on World Challenge cars, adds about 10 HP. Easy install, bolts directly to catalytic converters (no cutting and welding to cats). Fits manual and automatic transmission vehicles. Models with air pumps may require modifications (generally after 1996). \n This kit has been tested on a Mustang chassis dyno using a Horiba air/fuel ratio analyzer and on the road under real world driving conditions. Per the dyno charts you can expect over 12 ft-lbs of torque, something you can really fell in the seat of your pants. \n This kit was specifically designed for BMW 325i from 92 to 95. Other kits are available for later model cars, however, the software is different and design for specific models. \n Racing Dynamics software is designed for: \n \n - Optimized Fuel and timing maps at full and partial throttle positions.
\n - Improved throttle response under all conditions.
\n - Raised rev-limiters optimized for maximum performance!
\n - Top speed limiters removed if applicable
