I have a Nissan Snorkel and mine droans at 1600-1800 RPM. The Dealer's Workshop Foreman told me the noise mine makes is quiet compared to others he's heard.
I was looking into getting one this afternoon ( a snorkel that is) and the guys at the shop said that I would most certainly hear it. I guess this is normal for the navara.
Oi Juiced, got a pic of your Rallye 4000's. Thinking of getting some for the sports bar, just gotta make up a retractable bar to fold them down when I dont wanna use em.
My genuine snorkel is bloody noisy, I actually thought there was a problem with it as my patrol doesn't make anywhere near that amount of noise. Just goes to show how much air these things suck.
