ConclusionStrapped to Dynamic Autosports Mustang Dyno, the MX-5 responded well to the newly installed parts netting a total peak gain of 18 hp and 11 lb-ft of torque. Not bad for a naturally aspirated car by any means. The car not only felt more responsive as we quickly shifted through the factory six-speed transmission, but was more enjoyable to drive on the streets and highways as the new Racing Beat intake and Tomei exhaust and header combo presented this MX-5 with a more sporty feel and sound. With such a small amount of affordable sport compact vehicles using the once-popular FR layout being produced today, it's a good to know companies such as Tomei and Racing Beat are among the few who continue to develop aftermarket products for the sporty MX-5, as they continue to keep the front engine/rear-wheel drive tradition alive and kicking in an era of economy filled vehicles.
