Now that you mention that I wonder if mine is pre wired for it? Probably not as I have the 1ss dual exhaust

Well the wiring is the easy part. The hard part, if even possible, would be to get the control/function from the touchscreen. Software stuff like that is well above my paygrade! ...that being said, not having "factory" control allows for some cool hotrodding options. On my Iroc, the two window switches were on the center console. I added a third, factory switch, wired to the cutout. While not a factory option, it was about as "stock" appearing as you could ask for!

MUCH louder than stock NPP, and a whole heck of a lot cheaper!

Actually, The NPP programming isn't based in the Infotainment software. The NPP valve programming is located in the FSCM controller and I am almost positive it is there for all models. It's simply disabled for non NPP cars. So you would have to enable it in the software which can be done with HPtuners and 1 credit 50.00. The FSCM is a separate controller from the ECU, so you should be able to flash it without voiding the warranty. That being said, I prefer to use the performance modes switch and I have my NPP valves tuned differently for all 3 modes.

Well that's cool....I didn't know that! Pretty cool!

If anyone has the old one without the valves and is looking to switch to the new one, I will buy the old one.

Good info. Did you make your own valve setting using the hp tuner?

Not sure how new this is, I only noticed it today. Looks like Corsa finally has a valved rear section option for our cars.

Check it out here.

Yep there was a thread in the general section on it. It's been out since May...kind of pricey but part of me still wants to pull the trigger on it since it has no drone and a 12db difference between open and closed modes. I like my current Flowmaster NPP for the money but it's not perfect.

Side note you can get it cheaper through another vendor.

Honestly the thread should be here since it's a bolt-on modification.

On your flowmaster what's going on with it? I've eye balled it a couple of times.

Nothing terrible...it just has a little more drone(14-1600rpm) then I care for when the valves are open and when they are closed you can hear a hiss from exhaust leaking past the valves(only when standing behind the car).

King if you decide to bite the bullet and want to let go of the flowmaster let me know.
