Ah, some people just like flame wars lol...
It's been said before, elsewhere, that any Dyno is really only useful for comparing your own before and after, and that's what I'm sticking to. Mine measured 406hp stock on the dynapack, so all I really care about is if I get around 411 after intake, or 430-440 after headers and intake when I eventually go back for another run. If I go to a different type of Dyno after these mods and run say 380-390 for example, there's no useful data there to represent gains from the mods. In other words, it doesn't really matter what anybody got on a stock run, what matters is what difference they show after modding, on the same type of Dyno, same conditions, setup, etc. |

NPP frees up horsepower in the Corvette, SAE certified, Chevy won't bother to recertify the Camaro. No big deal. It bypass some restriction. Less restriction allows less backpressure resulting in a SMALL gain.
Get your damn head out of the sand and get over it. Edit: Not only was your above statement unnecassary, it added nothing and is probably completely wrong even if NPP only adds 1 hp. But, I'm not perfect so, no offense taken by your opinion, just let me have mine in peace my friend. |

Show us the data. Until then... We know it frees hp on the corvette. Therefore, the argument that it frees hp is grounded more in fact than your OPINION that it does not.

Not opinion. GM does not claim it adds any to the Camaro. They do however claim it does on the Corvette. And from these two facts you come to the conclusion that it adds it to the Camaro. Now I did ask my dealer, and they are not the end all be all authorities (even though they should be), but the answer was that NPP added no power. Putting a reduction in restriction at a point downstream of the greater restriction will not gain you anything. Enjoy the added noise if its what you want, but accept it for what it is.

As far as asking the dealer... the first dealer looked at me cross eyed when I told him I wanted a 1le, he was like uh what is that? You mean a zl1? (in February 2013). Therefore, if yours is anything like that guy... I wouldn't trust his exhaust knowledge. This has been said many times, just because gm did not certify extra power does not mean that there is not extra power. Really though, we're pissing over less than 6 hp. Therefore, we can agree to disagree and no one will be the wiser. |

I simply think that it's not to relevant what your Rwhp is cause there always going to fluctuate depending on what or who's dyno your on. Whether it's a Mustang Dyno or Dyno Jet or some performance shop altering results to get more of your coin.... I do agree with that Dude Ozzy though, Dyno's are great for measuring your Mod hp gain, before and after!(as long as it's not at a performance shop ) |

It's all about TOTAL amount of restriction in the exhaust system.
Freeing up SOME of the restriction means a little less TOTAL backpressure. A little less backpressure frees up a little bit of power. This is how a catback frees up a little power, and this has been proven on dynos time and time again. Even a little gain is more than none. For me, it's all about the NPP sound anyway. NPP valve closed is like a stock exhaust. NPP valve open equals a very small catback-like gain in power. This should be very simple to understand.

I guess my opinion is that if there is any gain, which I doubt, it is trumped by the increase in noise. I have no problem with competition vehicles being loud because the goal is to get as much out of the vehicle as possible, but minimal gains are not worth the noise. This may all be because I am older than probably many on this site. I would still love to see a before and after NPP test, but that may never happen As far as the cat back systems, having worked in the racing / performance industry for 15 years before my new career, don't believe every dyno result, especially those where the testing is done by the manufacturer. |
