Dual mode Exhaust Question for my LS2
I have an 07 C6 with the dual mode exhaust system and NPP package. I want a lil more out of my exhaust and will be removing the H pipe to do a thermal plate soon so now is the time to do something. What can I do to get a lil more power and sound out of it.
thanks 4 the suggestions.

The thermal plate (or any plate for that matter) will amount to next to nothing and I'd advise you skip it.
For a "lil more power and sound" I'd advise you do longtube headers. I have LG longtubes and the Z06 mufflers with the "muffler mod" and NPP in a box. I'm very happy with the setup.

You only have one or the other, dual-mode exhaust (Z06 muffler) or the NPP package. The two are slightly different. You also have one or the other as a non-stock item on a 2007 C6.

I dont have the z06 mufflers and pipes which are 3''. 07 cars only came with stock exhaust so I took system off of an 08 c6 with the flaps and added the NPP in a box to them so I can open and close the flap when I wanted to. Also from what I hear the z06 mufflers are quieter so most go with the 2" set up. I do agree headers might be the way to go. Can't I change the stock H pipe to a better flowing pipe?

I have a 2007 MN6 so I'm fully aware of the stock exhaust setup.
The Z06 mufflers (with the muffler mod) are not quieter than the NPPs. I've heard both. As previously stated I have the NPP in a box.
You can change the stock H pipe to an aftermarket pipe, which usually comes with headers. That's what I did.

I doubt that a different mid-pipe will give any noticeable power but might change the sound somewhat. You could always go with the '08 mid-pipe, it's an X instead of a H and should change the sound a little.

From what I've read, it might change the character of the exhaust note, more than anything else.
If you are after more sound under 3500rpm, but flaps open ALL the time is too much, get the NPP collars from Ed at Nakidparts.
Otherwise, yes, headers are what you want.

if you want more sound AND power headers are the only way to go. I have Kooks headers, catless x pipe, and z06 mufflers and everyone LOVES the sound. Not too loud when it's open, and no drone when closed.
Plus, the added power of the headers (and tune) is nice...

is that the cam that makes the car idle like that? I'm not sure I want that
I'm hearing allot of talk about LG long tube headers. What can I expect to pay for good quality headers and install
thanks guys!

Yes...The cam.
My American Racing Headers were about 2k installed. Probably should get a tune also, so perhaps another $300. I think you could be looking at another 40 ponies and much better sound.

Just installed z06 dual mode to base C6
I already had a x pipe from SLP that I got rid of ...louldmouth and loudmouth II... I couldn't tell any difference between them... both were loud...
I have a throaty sound now, haven't really had a chance to drive on interstate yet, later today I hope... love the look and they are not too loud with the flaps staying open right now.. waiting for the npp in a box to leave it quiet with the wife riding in it..
They z06 have the bigger tips at the rear, and I like the look of BIG...
