Has anyone put an NPP exhaust on an early model C6?
Was thinking about putting an NPP exhaust on my 06, which is an automatic. I think it will give me just about everything I want with an exhaust if I also did the mild-to-wild switch. I've looked at Corsa, Borla, B&B, etc. The NPP will give me the sound I want.
When I talked to two shops (both specialize in Corvettes) about installing an NPP exhaust on my car, the first question both asked was "manual or automatic?" One of the shops was like "I put one on 05 automatic and I will never do that again" and declined the job outright. The other said the labor cost would be too much and said he would put any other exhaust on there except an NPP.
Is there something about the setup of the early C6 automatics that makes that NPP a tough fit? I know it didn't become an option until 08 or later.
Is there a solution the two shops haven't thought of that makes it a little easier?
Also, if there is a vendor or a shop in Florida that someone knows of, I wouldn't mind driving a couple of hours to have it done by someone who has done it before.

The shops on the for sure 06 and newer are after the quick $$ of a cutback change, not sure about the 05. To get the NPP exhaust you will need a NPP in a box and this takes 1-2 hours to install and that is it. The 08 NPP is a bolt on for older vettes, the 09 and new NPP mufflers are different and you need the x-pipe to complete the install.

Use what the PRO's use - Thanks to LG, ECS, Vette Doctors, Corvettes of Westchester, Corvettes of Houston and the many other Chevy Dealers for choosing this system to install in their customers cars, they demand the best and so should you. If you have any concerns or questions about the quality or ease of installation feel free to call them an see why NPP in a box is their choice.
VetteDoctors (Carmen) “Your NPP system is the best on the market. Very easy to install & your service is second to none.”
East Cost Supercharging(Chris) “We installed one last week and I must say the product was very well put together and a smooth install.. Thanks”
Corvettes of Westchester(Chuck) "I can't say enough about the NPP in a box PRODUCT! The kits are first rate! EVERYONE wants them! PRICE IS AWESOME!
SHIPPING IS ALMOST INSTANT! What more could you want!?!?"
1. The vacuum source off the motor had to be extremely simple to get. No removing coil packs or trying to access the back of the plenum and break off the unused vacuum line. It does not use the booster supply, so no worry there. On the LS2 /LS3 it will take you less than 5 min to install the vacuum tap (no tools needed) our innovation, approved and tested at vette doctors.
2. Want innovations, I did not just copy the GM system. I developed a 100% new system where the control is no bigger than a box of Twinkies. All parts are enclosed in the box (no separate controller to install) and will be located 100% in the car (rear storage hatch) with both the wireless control and the vacuum controls safely housed inside so you have no weather issues. The power supply is in a heavy double shielded cable, 5 min no tools and nothing to pop off or remove.
3. Cost is $179 and will include everything needed, you just supply the exhaust. You just install the vacuum tap, run the provided vacuum line from the motor to the rear, run and install the provided power harness, install the control box and hook up the vacuum lines. The whole system will draw less than ½ amp, have zero drain with the car off and start either open or close. It is not designed to work with the car2u visor yet but will have Mild2Wild built in or ask about a custom unit with a foot switch.
4.Designed to work with both the B&B and the GM NPP system that are installed in a retrofit configuration.
like to see what your getting? - here it is
Here is the complete process
NPP in a box, a set of NPP mufflers will give you an incredibly easy way to have just the sound you want, when you want, if you have a pre-2008 C6. In my case, throw in a set of LG headers, and you have rolling thunder at the flick of a switch. The combo of the headers and the NPP in Wild gives you AMAZING sound and “HEY, LOOK AT ME!!!” volume…the tonality and sound is that of a NASCAR stock car at WOT outside the car, yet quieter and less drone inside the car than the GHL exhaust I was so fond of. The install is very straight forward, easier with a lift, but as has shown, you can do it on jack stands. Here are some pics and descriptions of the step by step process; you will receive complete illustrated instructions with your purchase.
NPP Mufflers waiting for Install
Factory Exhaust Removed
Drilling a ¼” hole in the rear well
Run the Vacuum Tube though the hole
Run the Vacuum tubes through existing frame locations
After dropping the rear sway bar, snake the NPP mufflers up and over
Attach the pipes to the mufflers
Connect the vacuum hoses to the NPP mufflers
Make sure your muffler pipes are straight and level
Muffler hardware done and vacuum tubing run
Connect power cable to the Seat Heater Fuse
And of course, a quick hit with our Polishing kit
That's all there is to it.....All that's left is to go out there and have a blast with your new found customized sound.

ok...
I have a A6 06, and I put the NPP on from a 08, it just bolts on... The muffler shop did the swap in 45 min...$75... I did the Mild to Wild NPP in a box, in about an hour.
The people you talked to most likely tried to swap a Bi-Mode off a ZO6, they are NOT the same... The ZO6 has 3" pipes and does not fit on a Auto... NPP costs more as they are a direct bolt on, and have a solid pipe in the muffler, unlike the ZO6 which has a perferated pipe, and does not sound as good. I love mine...

The shop you're talking to doesn't know what they're talking about or they've never done it or they don't know how to do it correctly
I put modified Z06 pulloffs on my '07 A6 and it took a few hours of work (and that included the mods to the mufflers to make 'em into "NPPs").
Cut the overaxle's off the stock system, weld 'em to the NPP's and it's a piece of cake

(oh and after the mod, they are 100% identical to NPP internally)

I have an 06 A6 and put the z06 bi mode on. All we did was cut the stock over axel pipes and welded to the z06 mufflers and re installed, cost $150 at local shop. He let me run the vaccum line while car was on lift and did the rest of the npp in my garage in 20 min. All in all it was very simple, i do regret going with z06 pipes instead of npp. The tips on the z06 are much nicer but not a huge gain in sound that i was looking for, so i will be going back to shop to do the mod on muffler to make the internals like the npp. Good luck!

You only need the NPP in a Box if you want to control it manually. It will work like it came from the factory just by running a small hose from the mufflers to a vacuum source on the intake.
You also don't need to cut the overaxle and do any welding. My shop installed a stock Z06 axle-back setup on my 07 A6 with no issue.

Was thinking about putting an NPP exhaust on my 06, which is an automatic. I think it will give me just about everything I want with an exhaust if I also did the mild-to-wild switch. I've looked at Corsa, Borla, B&B, etc. The NPP will give me the sound I want.
When I talked to two shops (both specialize in Corvettes) about installing an NPP exhaust on my car, the first question both asked was "manual or automatic?" One of the shops was like "I put one on 05 automatic and I will never do that again" and declined the job outright. The other said the labor cost would be too much and said he would put any other exhaust on there except an NPP.
Is there something about the setup of the early C6 automatics that makes that NPP a tough fit? I know it didn't become an option until 08 or later.
Is there a solution the two shops haven't thought of that makes it a little easier?
Also, if there is a vendor or a shop in Florida that someone knows of, I wouldn't mind driving a couple of hours to have it done by someone who has done it before.

Exactly, I had no issues with my 07 A6. I later installed 1 7/8" Headers with a 3" to 2 1/2" crossover pipe to match the NPP exhaust and still had no fitment issues.

I currently have a 06 A6 and I installed NPP mufflers off a 2012 a few months ago. I did have to cut some of the piping because it would not fix the stock h pipe. Right now it seems as the mufflers are just open at the moment. I still need to order npp in a box to close and open my mufflers. I thought it would be a lot louder, but its not. Is this normal? Im thinking of getting test pipes to get the sound I want.

An '08 NPP will work perfectly fine with your trans and existing midpipe, an '09+ NPP will require a new midpipe (09 + but not the catted midpipe..I think that started in 2012).
The zo6 Bi-mode will not work without modification due to it being 3" pipes ...your midpipe is 2.5" and some have said the auto trans and pipes hit each other.
I have a NPP on my '07 with the MtoW kit. I did everything myself on jackstands and it was pretty easy. I am going to Zo6 manifolds, Zo6 mid pipe, B&B fusion exhaust in 2 weeks if you are interested in buying my NPP. I am in West Palm and will meet halfway, or drive it over to West Palm and we can install together.
NPP units are pretty desirable and are worth more than Zo6 bi-modes. Mine will be for sale for $800 plus shipping and I am fairly confident I will easily get that for them.

How do you get the pipe on the passenger side in place?
I have a 2005 Automatic and when I could not get it off - i would assume putting it back on would be the same deal??
