Exhaust System

The exhaust system on my Fisher Fury R1 was and is one of the most problematic aspects of the car. Firstly, a 2003 fuel-injected engine is loud and requires a decent sized silencer, which adds weight. Secondly, it also needs a catalyst to pass the IVA test.

Being a front-engined car, the Fisher Fury R1 requires a complex 4-2-1 tuned stainless-steel manifold that leads out of the engine bay and over the chassis, then along the side of the car, through the left-hand-side sidepod. The space is severely constrained and care has to be taken to avoid burning the surrounding fibreglass bodywork. Their is also a lot of heatsoak into the passenger side of the car.

By using a mid-engined configuration, the exhaust route from the engine is both shorter and simpler, with less metalwork required, thus saving some weight. There will also be more space for the exhaust system and much greater free space around it.
