OK...whats the diff between ZL1 and NPP exhaust?? BIG diff in price.....

Juiced1 · 03-11-2013, 06:23 PM

Same thing. NPP is just the name for the system which is also available on the 1LE

coptzr · 03-11-2013, 06:29 PM

2 different part numbers. ZL1 #22874269 and NPP #22756148. $400.00 diff in price too.....with ZL1 being more

Juiced1 · 03-11-2013, 06:34 PM

Oh, pretty sure the ZL1 system is 3" compared to the 1LE 2.5"

coptzr · 03-11-2013, 06:38 PM

Thanks for the input......anybody else know???? just getting all the input before I pull the trigger..

the ZL1 is a 2.5" system. I have it. the tip angle is ever so slightly different than my NPP exhaust on my 2013 SS. The function is the same and I cant tell you about sound difference due to my black 2010 having a full built motor. But tips are dimpled the same (some said the tips were different sizes but they are also the same there. So to be honest other than a little bit of tip angle I say they're exactly the same. havent looked to see if there is a resonator or something on the NPP but ill go look now for shits and gigs.

Seems kinda odd then there is such a big price difference.....

The 2010 Sin · 03-11-2013, 10:36 PM

Truly. odd. But then again. CTS-V lifters are way more expensive than LS3 lifters and they're the exact same thing just different part numbers. GM does this all the time.

coptzr · 03-12-2013, 05:54 AM

Valid point!!! Still seems like a huge difference..

Snob tax. Ha!

All I know is I love my npp exhaust. Best sounding rig out there in my opinion without it getting annoying.

The 2010 Sin · 03-12-2013, 10:44 PM

Couldnt agree with you more, thats why my 2010 has the ZL1 exhaust and my 13 got the NPP option! :-)

Yeah, it was definitely worth the money. I love the quad outlets too.
