diff of 895 (?) or so cash. Yea there is a difference. My 1le didnt have it. so i ended up going borla atak. Not sure how mine compares in real world comparision but my car does rumble allot better.

I would say, if your going to buy a ss get npp.

Mine has the NPP. Dual exhaust, Dual tips on each side. I think if its not NPP is Dual exhaust single tips on each side..

Yep the dual mode (NPP) exhaust has 4 tips, 2 each side while the standard exhaust is a reg dual exhaust with 1 tip each side. The dual mode sounds a lot more aggressive and opens and closes 2 out of the 4 outlets depending on power setting to make it quieter during cruise but louder and more aggressive at higher RPM.

every 2013 ive seen so far not jus 1LE has had dual exhuast...one of my customers has a convertible and it had duals...thats why i ask

TJR1952 01-12-2013 07:44 PM

Its a option that you pay for. It is not standard equipement except ZL1.

beany323 01-12-2013 08:03 PM

stock mufflers have dual exhaust mufflers in the back. the npp gives you quad mufflers in the back. If you see 2 x 2 exhaust tips then it should have npp. normal is 1 x 1.

dual exhaust mode is the npp exhaust mode.

NPP/Dual-mode exhaust is the way to go, plain and simple.

Agree! I made them trade another dealer just for the NPP. It's awesome.

I have NPP and its plenty loud. My flanking neighbors have each texted me when I arrive home. It's that loud they can clearly hear the car in their houses. Al Oppenheiser even says this was their design intent to make a statement your neighbors can hear.

The Camaro NPP has different programming than the Vette NPP. On the Vette it's quiet at idle and loud at rpm. On the Camaro it's loud at startup then quiets down for a certain rpm range then gets loud again. The exhaust commander switch basically makes it loud or quiet around 3K rpm. When loud the car certainly drones more. I liked this at first but now appreciate Chevy's programming of the valves. I can actually hear my radio better now and talking on the cell phone more comfortably. But if and when I want to get raucous I can push the Exhaust Commander button and go loud again.

Oh, and when you're in the loud mode the backfire / back gargle is much more prevalent and delicious.

My 69Z28 came with RPO NC8 (Chambered) exhaust, it was also designed to garner attention but was killed after a few months of production as local law enforcement agencies complained to GM. My 1LE has NPP, worth every penny and the best sounding factory exhaust on a camaro in forty years:thumbsup:

How Does the NPP Exhaust compare to Borla Atak? Is the NPP still quiter or about the same?

beany323 01-12-2013 11:08 PM

from what i can tell the borla has a little more raspy growl. but i am only comparing from videos of npp vs the new atak i put in today. and didnt get it on the freeway today. think we need more milk. "i'll go" !

NPP is perfect, especially with the fuse pull. I can't speak for borla, I did however have that exhaust on my SRT4 years ago.

If I order a 1LE, I will go with the NPP exhaust as well. Being loud and obnoxious doesn't bother me at all. After all, it is a sports/muscle car, it should be that way. (Plus, it looks WAY better than the single exhaust outlets.) Interior drone wouldn't bother me neither. I would have the radio off half the time just to listen to that exhaust. The Borla on my Dodge Ram is loud and has some drone, but I love it that way.:thumbsup:

Love that Dual Exhaust sound!

OzzySS 01-13-2013 11:33 PM

stock exhaust, you barely hear anything...
NPP, you hear it when you open it up, and it's quiet at cruising rpms.
here's one of my vids from the dyno today for an example of the sound. the last time i searched on youtube, there was only one example of NPP, i think. my car is stock as far as performance mods, btw.

CrystalRedTintcoat 01-14-2013 12:38 AM

OK ... here's another highlight of the NPP with my son celebrating the sound!
