Adding 9 hp past the peak HP and shift point is like pissing in a dark suit....no one really notices. I still feel that is you are not buying it for the sound, its not a good value at all. I have not changed my opinion, just maybe stated it in a more politically correct way! To each his own.

When I say it sucks I mean it sucks! The sound sucks, there is none! It performs on a stock or lightly modded car fine but that's about it. What else is there to say about it.

I purchased my NPP so I am able to control the noise level inside the cabin with a switch.....I also like the look of the 4 tips vs 2

That's not past the shift point, you don't shift at peak you shift a few hundred past it. So that would be valuable to have that extra 10hp at the wheels in my eyes, my car peaks at 6400 but likes to be shifted at 6700 into 3rd for best trap speed! Before my cam I ran it right up to the rev limiter for my best times.

Changing the oil can have an effect on power output. You should have left it in there. Older oil will be slightly thinner and rob slightly less power versus fresh oil.

Thanks OP for posting. Interesting findings and makes my decision to order NPP for our 1LE a little more challenging.

But I wouldn't expect factory oil with 1300 miles would be significantly different from fresh oil with 50 miles. Assuming it were thinner, I would expect the new oil run to be lower power across the board, maybe worse at higher RPM. Unless you change the manifolds and cats I wouldn't expect much of power difference within the normal operating ranges. I wanted the NPP style and was pleasantly surprised with the NPP sound. |

I still dont understand the complains about the NPP; installed from factory, cheap, better looking, warranty, free flowing that can support huge HP, great sound and lighter. Show me what other catback adds for HP versus for the price. Go ahead, buy a damn 1300$ catback and stop complaining.
My NPP sounds wicked with high flow cats(2x louder!!). With headers, it would sound absolutly crazy and loud, but I would have the ability to control the sound. I mean its a win win. Great post OP, congrats! The NPP does have a very unique sound and it will hold a great value, like the old SLP dual dual in the 4th Gen.

Reasons to like NPP especially on the 1LE:
To me much more worth it than RS. Thank you OP for putting numbers on this debate.

Interesting. Wonder if weather the same on second run more of a difference would be seen, or just good old dyno differences on a different day.Also people on this site say catbacks make no hp over stock and this one cant be better then those, so maybe some power also from catbacks other then peak? Seen axelback graphs do the same , power before and after peak but little at peak. All food for thought

NPP seems great to me. It adds power,which I always knew it would but I don't understand why Chevy has not taken the time to quote the actual hp of a Camaro with NPP and also why why they haven't factored in the hp gain from the electric steering. It's pretty clear to me that a 2013-2014 SS w/ NPP probably has 441 hp or more at the crank. 10 or so for NPp and 5 for the electric steering.
