If you have a 2006+ Corvette Z06, you have dual mode mufflers (NPP) activated by RPM. Since their inception, wired and wireless controllers to manually open and close them have been available (like the PipeDreams MILD2WILD or M2W unit) for around $100. I didn't do this project to save money, but since I'm a DIY type of person, I knew I could do this in 15 minutes with locally available parts. The total costs of the parts will run about $45 with the controller in this article. You can however order a single channel RF controller online for around $15 making the whole project only ~$20. The controller below supports 15 amps per channel. If you don't use the controller below, be certain the controller you choose supports at least 10 amps, the same amp rating as factory.

Below are the tools, parts, and instructions that you will need.

Tools Needed:

• Wire Crimper/Stripper
• 7mm Socket

Parts Needed:

• Auto Zone etc... (Look in the auxiliary lighting section)
• 
• Pilot 4 Channel Wireless Remote $35 (Available at AutoZone, Pep Boys, Amazon.com)

• Littelfuse Add-A-Circuit Fuseholder (for ATO/ATC Fuses) $5
• 
• 1 - 18 Gauge Ring Connector $0.20
• 
• 1 - Male Push On Connector $0.20 (This must be the small mini connector type blade since it will go into a mini fuse slot. You can grind normal size blade connector as well with a bench grinder.)
• 

1. Pull back the floor mat and panel to expose the fuse panel on the passenger side floorboard.

2. Remove the seat heater fuse and the exhaust fuses. The seat heater is the fuse located at the top.

3. Insert the removed fuses in the Littelfuse Add-A-Circuit Fuseholder. It's a tight fit, press hard.

4. Insert the Littelfuse Add-A-Circuit Fuseholder into the seat heater slot.

5. The Pilot unit comes with four channels to control four devices, we are only going to use one channel for this installation. The red and black cables power the unit and all others are non-polarity and in pairs by color. It does not matter which order the channel cables (non red & black) are connected. For this installation, we will use the first channel, which is the gray wires. All other channel wires can be trimmed back or simply zip tied up for possible future use.

Strip about 1/4" of insulation from the black, red, and both gray wires.

6. Insert the red and one of the gray wires into the butt connector attached to the Littlefuse Add-A-Circuit and crimp. Be certain that the crimp holds the wires securely.

7. Insert the remaining gray wire into the male push on connector and crimp.

8. Insert the black wire into the 18 gauge ring connector and crimp.

9. The are two 7mm screws located in the lower left hand section of the fuse block. One secures the plastic fuse panel and is recessed and the other screw is located about 2 more inches to the left and in the foreground securing a metal box (amp??). Remove this 7mm screw attaching the metal box and attach the ring connector from step 8. This is the ground, it obviously cannot connect to plastic.

10. Insert the gray wire with the male push on connector into the "now open" LEFT SIDE of the exhaust mini fuse slot.

11. Your installation is now complete. Start the car and test the functionality by pressing the number one button (or the button corresponding to the channel you used) on the remote control. Your car will start in open mode requiring the button to be pressed for quiet mode at each startup.

12. After testing the unit, tuck all wires away with zip ties and tuck the unit underneath the metal box (amp?) to the left of the fuse panel. You can use the supplied velcro to better secure the Pilot unit if desired.

Frequently Asked Questions:

• I was told by a popular Corvette wireless exhaust controller manufacturer that their unit was specifically built for the Corvette, will this generic unit work?
  • Yes, it will work!!!! I'm not sure what "specifically manufactured" means. This is a really simple relay activated switching circuit. If anybody tells you different, they are lying! The unit must support a minimum of 10 amps which is the same rating as the circuit in the Corvette.The unit in this article supports 15 amps per channel. With that said, you should fuse the circuit for 10 amps, the instructions in this article do that.
• Who invented this technology?
• I'm not sure but DC RF controllers went mainstream in the 80's when car alarms started getting popular. Being able to wirelessly control your exhaust is no different than wirelessly popping your trunk or activating your alarm and having it flash your lights on activation. Since then various manufacturers have sold individual wireless relay activated units to control auxiliary lighting and cars with hydraulic suspensions as the main applications.
