The BF range of FPV models had the BOSS 290kw V8 motor, and was unique in the way that the stock exhaust had quad exits out the driver and passenger sides. By fitting a quad exit Manta exhaust system, the unique “stereo” sound of the exhaust note can be achieved, sounding many times better than the factory exhaust system. The Manta Performance exhaust also uses high flow, straight through mufflers, and larger pipework to unleash extra power and torque right throughout the rev range. The cat back systems are ideal if you already have aftermarket headers and cats, or are just looking for improved sound, while the full systems with extractors deliver the best gains, have a throatier sound, and are essential if you are performing other engine modifications such as supercharging. For most applications, the 2.5″ dual system is sufficient, but for the ultimate in flow and sound we have our full dual 3″ system, the only proper dual 3″ system available off the shelf for the Falcon.
