too bad.

Think it was confirmed that the valves still close at highway cruse with track mode.

Track Mode (V8 Only)
Use when maximum vehicle
handling is desired.
When selected, the Track Mode
indicator will display in the DIC.
When in Track Mode, the automatic
transmission and steering will
function similar to Sport Mode. The
accelerator pedal is adjusted to give
maximum control during the highest
level of spirited driving. The
Magnetic Ride Control will be set to
the optimum level for vehicle
responsiveness. If the vehicle is
equipped with Active Exhaust, the
exhaust valves will open.
Competitive Driving Mode can be
accessed through this mode by
pressing the button with this g icon.
There are attributes that vary by
mode shown below. Not all vehicles
have all features, depending on the
vehicle options.

Sport Mode
Use where road conditions or
personal preference demand a more
controlled response.
When selected, the Sport Mode
indicator will display in the DIC.
When in Sport Mode, the vehicle will
shift automatically but hold a lower
gear longer than it would in the
normal driving mode based on
braking, throttle input, and vehicle
lateral acceleration. See Automatic
Transmission 0 209. The steering
will change to provide more precise
control. If the vehicle has Magnetic
Ride Control, the suspension will
change to provide better cornering

equipped with Active Exhaust, the
exhaust valves will open earlier and
more often. Competitive Driving

I guess it doesn't mean open all the time when in Track mode...or i wonder if you map sound management to be in TRACK for each driving mode, it only truly open 100% if you are actually in TRACK DRIVING MODE, as opposed to just the sound mapped to track mode???

I bet if this is the case, people will want to do a fuse pull if they want open 100% all the time.

That thread explains exactly how each exhaust mode works in full detail. The valves still close in track mode when at speed. They will reopen above a certain rpm depending if you have auto or manual. Auto needs higher rpms to reopen. They also close in v4 mode on the autos. Only a fuse pull will keep the valves always opened. Luckily there are wireless and wired mods you can do to control the fuse. I did the wireless version to my car and it works great. I have my car exhaust set to stealth and wirelessly control whether the valves are opened or closed with a button. I posted a thread about it with a link to the how-to

The exhaust is louder on cold starts and it has nothing to do with NPP valves. It has everything to do with cold start fueling and is temporary

[MikeyCamaro]

By looking at the sound review video, it looks like the valves are pretty far rearward and being back there and subject to things like condensation, I wonder if they need to operate at least occasionally to prevent them from being corroded shut and frozen in one position? Something to think about.

Drive mode won't stay in track, but if you go into
settings->Drive mode->Engine Sound Management

You can switch it to track, and it stays there.

It's definitely because of the cold start vs when the car is warm and has been running before starting again.

right but does do the valves stay open all the time, even when foot not on the gas? Others here saying no, it closes at say...highway speed if just maintaining speed...

anyway...IDK.

There was a thread about the NPP fuse pull that had some good info. The guy did a couple drives with and without the NPP fuse out and noticed it louder with the fuse out on the highway. It would make sense Chevy would tune it to prevent any drone on the highway cruising speeds.

No. It does not stay open full time in any mode unless the fuse is pulled. Full details here:http://www.corvetteforum.com/forums/...ck-result.html our cars have identical functionality

[DenverTaco07]

Thx guys - lots of help.

[bybcous]

Anyone else notice that there car does not go into v4 mode when in track mode? I still have watched it switched back and forth in other modes but never leave v8 mode in track.

This would be very interesting to confirm with others. All the info I have read, even from one of the engineers on the FNR tour have said it will still use AFM in Track mode. But the engineer did say a lot of variables would be taken into account for it to activate. I took this to mean the car would be less likely to use AFM in Track mode unless you were just poking along with a fully warmed up car.

[EricTheCamaroGuy]

Drive mode, exhaust mode if you have dual mode exhaust, temperature of startup (cold or warm start). Cold start, exhaust valves stay open longer

[corsa636]

One question, is it possible to calm down the (cold) start up of an Camaro V8 NPP (manual, EURO version if this matters)?


Is there a possibility to close the valves right from the beginning?
