I hear intake noise with the k&n as is too, but the idea of making it louder and adding a visual mod to the front excites me!ha.
Good shout with the piping. That was the 2nd option I was thinking of. Seen some ready made tubes for the 350z. But nowt for 370z.
Don't really fancy using cheap universal eBay piping, but might give it a try as a first go 👍
