I'd really prefer a very quiet 100 more hp...when people decide to f around I'll just blow their doors off and they'll think again before messing with another Z

If I nail it...you'll know whats up...otherwise, you would never notice me. Thats the way I like it.

You've got open dumps and you're able to "keep it discreet"? Sound clips or it didn't happen! :roflpuke2:

If you drive normal then you can most definitely keep the noise down. Even going easy it's not quiet but it's not obnoxious.

I like loud but that mustang sounds like a vacuum cleaner to me.

Wow! That was actually very quiet unless it was getting banged on!

This was what I was thinking when it came to open dumps:

Well, that would an open exhaust. :D

Having open dumps on just the waste gates will only get loud when the waste gates open. :driving:

I have the Berk exhaust with 3" down pipes and my car is only slightly louder than stock as long as I stay off the boost.

I have heard Old School's car and if he wants he can keep it quiet, but whenever I am around it always seems to be so loud for some reason. :stirthepot:

think most of you are missing the point of the sc kits avalible for the 370z. The whine is usally from a roots or twin screw type supercharger, the ones on the z is centrifical supercharger and theres a reason for that. Do you honestly believe u can fit a roots blower ontop of the engine and have it under the hood? its a matter of space.

She is a bit throaty at idle...but the way I drive...no one sees my coming. Dual 3" aam has a nice sound at cruise...when the wastegates open...traffic parts. Lol

Truth. But the Stillen 350Z kits sat on top, and needed a cowled hood retrofit to fit it underneath. You could probably engineer the same on the VQ37, with a modified manifold, and need the same cowl top.

Actually it can be done I bet, but after the Stillen 350z SC (roots) and how poorly it performed no one is going to invest in one for the VQ motor.
