The 5.0L BOSS supercharged Coyote/Miami motor in the FG FPV range was introduced when the previous 5.4L V8 could no longer meet emissions standards.
Producing a huge 335kw, the performance of this engine was nevertheless hindered by the restrictive stock exhaust system, and substantial gains can be realised by fitting a Manta Performance exhaust upgrade.
The stock headers and cats on the 5.0L FG have been proven to support over 400rwkw, and a cat back exhaust is all that’s required unless you are doing serious performance modifications. The full systems with extractors have a throatier sound, but are really only necessary if you are chasing high power figures.
High-flow straight through mufflers are used in all FG Coyote/Miami systems to control drone, while still allowing maximum performance, and giving off a deep throaty tone.
For the ultimate in power and sound, the 3″ dual system is the only one of its kind available for the Falcon, while the 2.5″ dual generally provides more than enough flow for most applications, and still sounds fantastic.
