Primary Designs

Primary Designs are active long-term innovators. As such they had already claimed R&D tax relief with Easy R&D and were well versed with working with our team. 

Their latest claim was for the research needed to develop and test an ultra-lightweight exhaust system for the Porsche Cayman 718 GT4. The challenge was to release more power through a modular exhaust design system while achieving a noise level and acoustic qualities that were acceptable for both track and road use, while still achieving rigorous vehicle emission controls. The solution also had to be lighter than previous models and the standard OEM exhaust, but with sufficient longevity and durability to make the product value for money. 

Extensive rounds of road and tracking testing were followed by re-engineering the exhaust system and dyno-power testing was required to achieve an acceptable noise and resonance level, while maintaining a significant advantage over OEM exhausts in terms of the power output.
