Switching to NPP on 1LE SS, What parts are required...
What parts are required for taking an NPP from someone else's car and putting it on my own? When I say from someone else, i mean someone upgrading to something else or even a wretched with an intact exhaust. I'm trying to figure out a cheaper way to get the system than going through the dealership.
Also is it something I could install at home? Are there vacuum lines involved? Could I buy an NPP system from a third party(camaro owner) and have it installed at dealership to avoid warranty loss? |

The catback itself will bolt right up. You'll need the rear diffuser for the quad tips and an NPP in a box to control the exhaust mode. Yes, you will need to run vacuum lines.

I just recently installed the NPP exhaust on my 2010. The seller said the exhaust was pulled from a 2013 ZL1 - It literally bolted right up. I chose to have it installed at a local shop and it took him roughly an hour but a portion of that was talking with him and watching the process. He had to use a long crow bar to pull off the upper most hangers and he didn't like the way the stock diffuser was installed (plastic snapped into plastic).
I opted not to install the NPP Vaccum kit and try the exhaust wide open. It sounds great and is not overbearing in any way. I get a little sound in the cabin but it's not annoying at all and music easily covers it up. The way my NPP exhaust sounds is how I feel the Camaro should have sounded from the get go - I reccomend it highly.

I only close my flaps on the highway and thats not because its unbearable in anyway its just nice tohave the option and quiet it down a bit. If installing the vaccuum lines is very difficult or relatively expensive I would suggest avoiding it, you will love that exhaust as Fan stated above its how these cars should sound from go!

With the headers, I prefer the sound with the exhaust closed.

Ok so it bolts right on, and I would probably just leave it open, so i dont need to do vac line. I don't have to buy the NPP in-a-box thing do I? that just controls if the exhaust is open or not?

Why bother getting a dual mode exhaust if you're not going to use it?

I just installed my kooks and catless connectors and def like it closed while driving around town but it does sound sweet with them open too.
I used npp in a box from http://forums.corvetteforum.com/c6-c...oductions.html It came with everything needed. I lengthened the wires a foot so I could tuck them better and I bought longer hoses for the exhaust from O'Reillys for 4 bucks so I could run one to each muffler out the trunk.

The sound of the NPP over the stock is way better, and I don't really want a really loud after market exhaust bc I just bought the car and have extended warranty. I figure I stick with GM parts they won't hassle me at all. (not that they have the right to if its just exhaust, but i dont feel like even arguing) A used NPP is easy to find and also is much cheaper than getting some new after market stuff.
Having the ability to close them would be nice, but if its all kinds of extra work, i dont really care. |

I am on the verge of buying the NPP exhaust to retrofit into my 2013 Camaro 1SS. Just to make sure I have everything correct all I need are the 1LE diffuser, NPP exhaust mufflers, and the Mild2Wild kit with perhaps longer hoses? I plan on JUST wanting the ability to switch back and forth between open and closed butterflies. I just love the sound of the NPP mufflers and am hoping this is absolutely all I need.

This is my car stock with the NPP. I love that is can open a close. You can see the valve in the video just above the left tips and watch how much it opens and closes just under the short time of the video. I would take the time to run the vacuum lines. It makes the car so much more livable day to day. In my opinion. |
