Are Z06 and NPP mufflers different construction?
I want my base C6 LS2 to sound somewhat louder and deeper in tone. Of course the LS2 is not going to sound exactly the same as an LS9 for many reasons.
I am considering installing Z06 mufflers on my 2007 LS2 with NPP in a box.
I think I can seal the 2 inch H pipe to the larger diameter Z06 mufller inlet pipe.
My question is this: Is the Z06 muffler the same muffler used for the NPP exhaust option or is it a differently baffled muffler inside?
I appreciate any thoughts. Thank you.
It's got so it seems to me that the Internet has created a lot more Horses A$$'s than we have Horses!

Visit a local Corvette club in your area and ask to hear people's cars there.
Making an exhaust system louder is easy, the hard part is getting one to have the "pitch" that you want. This is why you want to listen to numerous systems.
Also, be sure to ask about "DRONE." This is quite uncomfortable auditorily.
Zo6 mufflers are unto their self, yes, they are different than base models NPP option. They have their perforations built inside muffler whereas NPP has it's perforations not in muffler but in tail pipes.....but YES, Z06 mufflers ARE different. If you have NPP the idea behind the perf means you have....

Like I said above, the perforations are in Z06 mufflers whereas the NPP options are NOT in muffler but in tailpipes (meaning you have what creates the sound you seek w/NPP) NPP in itself is SIMILIAR TO but NOT exactly same as Z06. NPP was designed borrowing SOME features from Z06. They are NOT exactly the same though....I have owned a '09 Z51 Roadster w/NPP which I sold to replace with a '10 Z06.....I HAVE looked into both, and owned BOTH. Hope this answers your question. The sound you seek will NOT be exactly like Z06 however. You might get closer to LS9 sound because of cubes difference. 427 (7.0) -vs- 362 ((6.0) -vs- 378 (6.2)The 427 is a DEEPER throatie sound when low RPM's and more race car sound when higher reving (7000 rpm red line). The LS3 w/NPP (on) sounds like a race car ALL the time w/2 1/2 in pipes. Z06 is 3 in pipe. Don't know about LS2. The LS7 has MORE DRONE period. Because of cube size. More than LS9 as well.
