Retrofit NPP Exhaust Onto 2015 2LT V6
I know that it will physically fit, but as far as I'm aware I won't have the necessary hoses and/or vacuums for the NPP to work as it would from factory, with pressure sensitivity and activation. I like the idea of being able to control the drone and/or volume at the flip of a switch. Can I have one without the other?
1. Is it true that I wouldn't have the pressure sensitivity/RPM activation without additional parts and labor beyond the exhaust itself (planning on buying used NPP)? 2. Would I still be able to use a Mild2Wild or similar Controller to control the NPP valves even without the pressure gauges and activators? My favorite option is if I can still control the NPP valves without modifying anything under the hood to allow RPM activation. My next best option would be MRT v2.0 with Dual Tips. Thoughts, ideas, insight?

How so? NPP would be around 600, with about 200 for relevant wiring and harnesses for the controller.
MRT v2 is 600 new, with about 100 for dual tips, and 100 for the welding of those tips. Price looks to be about the same, except with one of them I get to control the drone (ideally). I like to buy OEM used and aftermarket new.

If you can buy the exhaust you can buy the Vacuum diaphrams and there is not that much too it. A storage tank, electric going in through trunk...Here look at the instructions for a Forza three way switch.... it shows the stuff pretty well.
http://www.camaro5.com/forums/showthread.php?t=411551 And though you could create a switch for the exhaust it would be a pain, and no the switches will not work with out it hooked up. Maybe you should look up some threads on retro fitting or talk to Forza Steve

Why do people like these so much? Do the open/closed valves really make that big of a difference from each other?

Search in the LFX forums. I added a complete NPP system when I had my V6 Camaro.

A friend of mine talked to the GM Engineer in charge of the Dual mode exhaust at the Find New Roads event. They talked about this specifically and the engineer indicated that it's very complicated to attempt to add after the fact. It's not just slapping it in. In the Gen6 he flat out said forget it.
The best solution some came up with was a manual switch, but you're better off just finding a nice aftermarket exhaust. |

I have a friend who has a 2014 1LT Convertible, a couple weeks ago, I just helped him find a NPP from a 2012 2SS and installed it on his car. No need for modification for the exhaust to fit on a convertible/V6.
Regarding the flaps, they will stay open all the time. If you want to control the flaps, you need to buy the NPP IN A BOX. This is for those who didn't have the NPP setup from the factory. I never done it, but according to the website, it only takes 5 mins for installation. http://www.nakidparts.com/id78.html With this, you will have access to control the flaps for, OPEN ALL THE TIME, OEM SETTING (3500RPM+ OPEN) About how it sounds on the V6, for loudness, my MRTV1 is a little bit louder than the NPP, but the NPP is still pretty loud. What's best, is that the NPP is at the same time deeper!! If I had the choice to go back, I would definitely choose the NPP for only spending $500 and maybe $180 for the NPP in the box. For my MRTV1, I already spent 430 for the exhaust, 140 + 100 labor for the quad tips, 200 + 100 labor again for the SOLO J PIPES to get rid of the drones. =( |

Because it sounds bad ass for a stock set up, no drone, loud under acceleration and quiet when needed! You should check one out!

Yes the open/ closed make a real big difference especially with headers. And the sound is really good.
https://www.youtube.com/watch?featur...&v=u6NEyQbdnb4 Any way here is a video I did without cracking up after my wife teased me in her piggy slippers saying I was showing off...lol I had to remake it over and over because I could not stop cracking up.... Someday I will remake it and take it for a drive with a go pro or something , during the video I do switch to quiet mode anyway....

Before you purchase an NPP exhaust system to retrofit to a Camaro that does not currently have the NPP system, what is it you intend to accomplish?
In the second option, if you intend to be able to retrofit your car as it if were an original factory installed option … sorry, not going to happen. Why? Because you need to have a means to operate those valves and if your car was not equipped with NPP from the factory you will not have the necessary solenoid valve, accumulator tank, vacuum lines and ECU programming to make it all work. Now, some have advocated getting a product called Mild2Wild NPP in a Box. Before you take this approach, you need to understand what is involved. NPP in a Box gives you a vacuum solenoid valve, a remote control relay, a couple of remote transmitters, some vacuum tubing and a component to tap into the engine manifold as a source for the vacuum required to operate the exhaust bypass valves on your NPP system. Missing from the NPP in a Box is a vacuum accumulator tank which stabilizes the vacuum that is otherwise quite unstable coming from the engine manifold, and your ECU is not wired in to control the valves. You will be using the remote control to manually open/close them. IMO, this is a Rube Goldberg solution. You might think, OK, I can live with this. But, if you think that you can install the NPP in a Box in 5 minutes and you’re done, dream on. You will need to tap into a vacuum source, route vacuum lines, install the vacuum solenoid valve, tap into an electrical source for the solenoid valve and test everything. You will also probably want to acquire new rear diffuser for the 4-tailpipes. What you end with is a manual control for your exhaust bypass valve. But, remember, the vacuum will be quite unstable because you will be missing the vacuum accumulator tank. As you vary the throttle on your engine, the vacuum will rise and fall as you vary the throttle position. May not be a problem, but that is why manufacturers include the accumulator tank with vacuum actuated devices. Your total cost is going to the cost of the NPP exhaust system + about $200 for the NPP in a Box + a rear diffuser to accommodate the four tail pipes + your time to do all this. I would not be surprised if you end up spending close to, if not more than, $1000. Even more, if you install a vacuum accumulator tank. If you want a true operable dual mode exhaust system to retrofit to your car which does not currently have his option, then the NPP route is a poor choice. You should be looking at an electrically operated dual mode system. Something like the Varex Xforce system. (By the way, I am not in any way associated with Varex … I just like their products.) These electrically controlled units provide variable bypass valves that are remotely controlled using a small remote transmitter, do not require tapping into vacuum source and at the end of day will cost about the same as trying to retrofit the NPP system to your car. You can read more detail on Varex Xforce systems by going to their web site. You can also do a YouTube search for "Camaro Xforce" for various videos on installs and results. Make sure you fully understand what is involved here and what the actual outcome and costs are going to be before retrofit your existing exhaust with a dual-mode exhaust system.

Do you think that I could control the valves between open/closed with either the Forza or Mild2Wild controller, without vacuum activation?
