The stock exhaust for the FG XR8 sedan had a dual exit out the driver's side only. However for the ultimate in looks and performance, Manta is able to offer a quad tip exhaust system, exiting out the driver and passenger side. This system does require modification of the bumper, to allow for the extra cut-out, but the results make it more than worthwhile! The dual exit design gives the Falcon a distinctive "stereo" sound, due to each bank of cylinders exiting out separate sides of the vehicle, rather than both coming out the same side as with the stock exhaust system. 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. High-flow straight through mufflers are used to control drone, while still allowing maximum performance, and giving off a deep throaty tone. Everything needed to install the exhaust, including a new chassis bracket for the passenger side, is included in the package.
