Exhaust Commander Elite All-in-1 NPP bi-mode exhaust retrofit kit

The All-in-1 bi-mode exhaust retrofit kit that we have been selling for years works on all C6's 2005-2013.
Its always been 100% Zero Battery drain since its inception!

With this bi-mode vacuum retrofit solution you get everything you need to control your retrofitted
bi-mode exhaust!

The Exhaust Commander Elite with rpm opening option we developed is also available available with this kit!

This NPP vacuum retrofit kit includes the wireless controller with one button keyfob remote, and all
of the necessary vacuum lines, vacuum solenoid and wiring to complete the control system installation.
It will give you full open / full closed modes and gives you the ability to switch between the modes
instantly using the supplied One button wireless remotes.

Typical install time is around 1 or 2 hours.

NO holes need to be drilled in your car when you mount the solenoid box outside of the car, and everything could be removed without a trace if you wanted to.

These systems are assembled and tested by Us, right here in the USA!

Quick install summary:

1: The engine vacuum tap used is the correct GM bi-mode vacuum port on the back of the
intake manifold, just like the 2008-20012 NPP C6, Z06 and ZR1's use. Not the brake booster or other critical
engine sensor systems. Do it right just like the GM factory does it. The GM engineers that designed the bi-mode exhaust system know the most reliable way to tap vacuum for the system is at the rear intake vacuum port.
The vacuum line is run above the tunnel plate from the engine to the
vacuum solenoid unit and then you hook up the vacuum lines to the butterfly valves on the mufflers.

2: The solenoid box is mounted outside the cabin requiring NO HOLES need to be drilled to install the system.

3: The wireless controller is located in the passenger fuse panel area just like all my innovative Exhaust Commander controllers allowing controller upgrades when they become available! The power cable is run
easily from the passenger foot well area to the rear of the car by tucking it underneath the trim panels.

4: Once everything is hooked up, Start the car and enjoy your fully operational bi-mode
exhaust system!

Very cool.

 

How to get the vacuum cap off the back of a LS2 or LS3 manifold.


I have installed over 20 of my NPP retrofit systems personally and have popped that damn cap off so many times I have it down pat and can do it in 5 minutes or less now.

Here is the secret.: Use a small x-acto knife to score / cut through the the place where the cap twists off at. There is a little groove where you can place the blade and then score / cut the cap off. If you can get a decent score on the line or even cut through it about 1/3 to 1/2 way it will twist right off with little or no effort at all.

Hope that helps and enjoy you bi-mode exhaust!

Way to go JB, that thing is a monster!

Can you tell me how many keyfob remotes come with your kit.

 

As many as you need, there is a drop down menu that lets you pick 1, 2 or 3 remotes.

Ben

 

Just placed my order! The factory vacuum mounting location was my deciding factor.

 

Looking forward to hearing how you like your bi-mode exhaust!

I installed the kit this weekend and all went well but that damn cap, it is the biggest pain in the A**. There is no room for a regular hand to get in there to remove it. We spent 2 hours messing with the cap. Your instructions need to have or give a better instruction on this instead of just saying to just twist it off. it is very miss leading!

Besides the cap issue (instructions) it is a great product.

 

The cap is a PIA..I used an exacto knife duct taped to a nut driver to saw it off.

 

Yes the vacuum cap is a PITA, no bs about that. Instructions now say try and twist and then cut if needed.

I have been able to twist some off, and some others I had to cut off, it all depends on the car.

I am glad you got it, and you should know that you have used the CORRECT GM vacuum tap area for bi-mode exhaust.

Here are a couple of pix of the offending vacuum cap:







Glad you have your bi-mode exhaust up and running.

Ben

 

Ben, my DASH unit is up and running as well, I (my son) had to virtually cut thought 3/4 the way to get the vacuum cap to break off. It took someone like my Son with longer thinner arms and hand to get in there to cut it off.

It is working as designed.

 

Thats great news!

Glad you are enjoying being able to open and close your retrofitted bi-mode exhaust right from the dash DIC! No remotes needed.

Have fun and make some noise out there.

Ben

 

I would like to make this mod to my '05. Where do you suggest we purchase the mufflers? New, used, GM or aftermarket? How much for the mufflers? Thanks!

 

There are two different factors to weigh when buying bi-mode mufflers.

Save Time, or Save Money.

If you want to save time, buy a set of GM 2008 NPP bi-mode mufflers.
They are a direct bolt in and don't require any modification fit your car.
Used sets run about $900-1100 and are fairly rare to come across.
New sets from a Gm dealer will vary in price depending on which dealer.

If you want to scar money the get a used set of 2006-2010 Z06 bi-mode mufflers. They ARE NOT a direct bolt in To you car becaue they hav 3 inch over axle pipes. You will need to cut the over axle pipes off you stock mufflers and hen have them welded tou the Z06 mufflers.
Used Z06 mufflers sell for between $300 and $500.

Once you have your mufflers all you need to get them functioning is Exhaust Commander All-in-1 NPP retrofit kit.

If you need additional info, let me know.
