The Spoon N1 muffler was developed and used on Spoon’s race vehicles and is the ideal muffler for the street and circuit enthusiast. The N1 muffler provides significantly improved exhaust flow and can be used with the stock b-pipe as it uses stock style flanges. In addition, the N1 muffler is one of the lightest available, weighing only 7.9lbs (3.5kg). The tip is 65mm, same size as stock, providing a subtle appearance. Can be fitted with a sub- silencer to reduce sound level.
