SPOON Sports N1 Muffler Kit Honda Civic FL5 2023-2024

In 2021, we raced the Spoon FK8 at the Thunderhill 25 Hours Race using the N1 Muffler kit. Exposing the driver to excessive exhaust sound in endurance races can cause unwarranted fatigue. On the other hand, when the exhaust sound is too modest, it may lack the ability to keep the adrenaline going and cause the drive to lose focus. In terms of spec, the N1 Muffler is a proven product. Running the product in a long-distance race allows us to gather data to understand how the sound affects the drivers. Feedback from the drivers were that the exhaust note helped them to concentrate throughout the race, but the sound was not excessive to cause any extra fatigue.

The N1 Muffler Kit for the FL5 was developed utilizing all the data and experience we were able to obtain from such real driving mileage. The initial layout of the system like the pipe diameter and silencer placement were determined from simulation data acquired on a flow bench. The development was finalized after repeatedly testing on an actual car. Anticipating turbo upgrades, increased boosts and of course racing, the diameter of the front and main pipes were finalized at ϕ70 combined with a ϕ145 bullet-shaped silencer and a ϕ80 end pipe. Adhered the dual exhaust style similar to the FK8 product. Please enjoy the Honda sports performance and sound with the Spoon Sports N1 Muffler Kit.
