The FM GT Mustang produces 306kw from the factory, which with a few modifications can be seriously increased. When it comes to performance enhancements, the best place to start is with the exhaust system. The performance of the Coyote engine in the Mustang is hindered by the restrictive stock exhaust system, substantial gains can be achieved by fitting a Manta Performance exhaust upgrade.
The stock exhausts on these vehicles are a twin exit design, meaning fitting the Manta exhaust gives the Mustang a distinctive “stereo” sound. After some extensive research and development work, we have come up with various combinations of High-flowing, straight through mufflers and hot dogs to not only control drone, but also allow us to maintain maximum performance, whilst giving off a deep throaty note, with a noise level to suit everyone’s need.
