NPP-just noise, no additional power? - Page 2 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

If you are only talking about cat-back exhaust, there's next to no performance gains in doing that so it's all personal preference on sound. Look here: http://www.camaro5.com/forums/showthread.php?t=21289

Listen to the different exhaust clips and pick which one you like best and go that route. If you're in love with the way the NPP sounds then get that. I just think it's really overpriced and you can get comparable sound for about $200-$300.

There was also no gain reported for the change for electric power steering. I don't think Chevy wants to change output officially when it is hard enough to get insurance on these things for the young guys and 10 more crank HP would put us over the Vette.

Here is what I learned about adding NPP to a non NPP 1LE.
Basically NPP improved power at the end of the LS3 power band.

Between 6250 and 6500 RPM...which is basically pointless, should be shifting before you hit redline anyways.

Perhaps if you intend to remain stock. However, when you cam up the rpm band will move up and NPP would be better than standard exhaust.

So the short answer is yes, it improves performance, but no it is not a magic bullet that improves every aspect of performance.
Yes, I would recommend NPP to a friend.

My advice, if you like the look, sound, and behavior of NPP, then order it.
But dont expect NPP to bump you into the next class of racing.

Few things in life improve things all by themselves.

Good luck with all those tickets for being too loud.

As far as increase in power goes for just the NPP, no idea. But mine with the NPP fuse pull and.a CAI and vmax was dyno"ed at 409rwhp, make what you will of that number.

Something in between the NPP, eps, and 1le package is ampimg it up...

my opinion is the NPP is awesome, love the tips, love the sound.

The NPP with a fuse pull is straight piped. Closed the exhaust routes through the mufflers. Open, it bypasses them. Doing a muffler delete gives you the same sound for $50.

And it sounds great

Look at any catback, it costs as much as a NPP, but its from factory and youre sure its legal. I say its a bargain installed from factory at this price. But yes it costs more than a muffler delete/cat delete.

I have a 14 RS, a friend of mine was going on about how he thought it was one of the best sounding V6 he has heard.. I dont k ow about power..but sounds good

theragtopguy · 01-31-2019, 07:48 PM

I don't really know if the NPP gives a HP gain, I'm sure if it does it is not much. I pulled the fuse on mine so it's open all the time and I love it!

Put a CAI brand Cold Air Intake on it right after I bought it and that allegedly gives an extra 10 HP.

All I know for sure is that combined at wide open throttle going thru the gears, it sure sounds badass!!!!! I love it!!!!!!!!!

you do realize you posted on a thread from 2014 that doesn't even pertain to a V6 car?
