Intake Sound Questions
 

Considering what intakes to get when I pick up my Nismo.

So, I'm wondering if anyone with either the Stillen (either generation) or K&N typhoons - could comment on how they sound. In cabin and out.

Any good youtube videos w/out aftermarket exhausts taking away from the sound would be great too.

Thanks for the help. :bowrofl:

Stock is like, weeeerrrmmmmmmmmm

and the stillen is more like a wurrrrrmmmmmmmmmm

If only I could give you rep for this... :icon18:

but at what RPMs?

One of the key differences between the factory intake and any aftermarket mods is the removal of the sound baffling system. It keeps internal engine noises from coming out the intakes, because most everyday consumers find them objectionable or worrying. So with e.g. the Gen3 or whatever, you will hear more ticking and tapping and whatnot than you did before, and if you're the paranoid type you might think you have a sticking lifter or something like that. It's just fuel injector noise and general engine noise, louder than before. In any case all of that's mostly at idle.

At speed, they just sound, uh, meaner and louder. Youtube could help you out, although probably most people who install them also have aftermarket exhausts.

(Note that in a dyno video like the 3rd link above, the very high-pitched whine is from the dyno itself).

As for in-cabin, that's harder. I can offer you some track vids I took, but it's hard to separate which parts of what you're hearing are the headers+exhaust vs the intakes, and they're all with the windows down too. Here's a jump into the middle of one just before a ~4K->redline run in 3rd:

Simply the best description EVER! :rofl2:

Thank you for the help WSTAR - that was the exact information I was looking.

Awesome :tiphat:

I love the sound the stillen intake makes.

The "wummmmmm" guy summed it up best.

Am I correct in assuming there is no tune needed for the Stillen Intakes, both generations.

You are correct

I thinking of going with the early gen Stillen (really don't feel like removing the front bumper......:ughdance:)

Has any had alot of experience with the short Stillen Intake?

Anyone?

Sorry hoss, I have the G3 long tube. The noise is the same but I don't think the HP result is.
