NPP fuse pull sound - Page 3

dennis@hixsonnet.com · 03-21-2016, 07:19 PM

pulled since day 1.... and love it..

Now when Borla and Corsa come out with their NPP exhaust I may consider putting it back... I like Corsa because its basically on or off, no middle ground

The Valves before the muffler are for the cylinder deactivation mode. The close partially when in 4 cylinder mode. Not on the manual cars...

I pulled mine and I really enjoy it. It sounds much nicer than rattling NPP valves.

I built my wireless setup by copying how they did it on the c7

How much of a difference is there really??? Dont wanna pull so I could use stealth if needed, but if the noise is that much better , count me in.

Just pulled it out tonight. Yeah that fuse is definitely not going back in. Sound is noticeably better!

Once it's pulled, 100% open in track mode, correct?

Yes. It's 100% open. I use sport driving mode but keep the sound management option at track for all modes.

They are 100% open 100% of the time no matter what mode since without the fuse the computer can no longer control them, they default to open without control.

I would be interested in seeing the pictures you took.

So it would be "track".. I'm confused with track and sport as the difference.. But I think it just matters on steering, exhaust will be full on regardless of the those two modes, right?

It doesn't matter what mode you're in if you pull the fuse.
With the fuse in, I can detect no difference between sport and track in normal driving (though Track does change some other parameters.)
