Do the npp mufflers have the same sound as the z06 modified mufflers or even the zr1 mufflers?

NPP and Zr1 has a little bit deeper sound to it vs modded Z cans.

Using standard mufflers assuming they all have the same engine tied to them, the order of loudness aka least flow restriction is:

1) NPP
2) ZR1
3) ZO6

(If I recall correctly) and I am pretty sure I do from all the forum research but correct me if I am wrong.

Not sure about any "Zo6 muffler mod"

When I had my Z06 mufflers with the muffler mod done to them installed, there was another Vette having NPP's installed.

The owner walked over to me and said that my mufflers were louder.

Listen to my Z06 muff. with the mod in my signature. Jeremy Formato did the mod and the install for me. He's up by you isn't he?

Na, Formato is in Tampa. I have tried calling him about other stuff and he never picks up the phone or tries to call back after I left a message.
I bought a set of npp's from Justin (juic3d) and haven't put them on yet. Just wondered what the difference were between the 3 mufflers.
