i plan on installing some pfadt engine mounts when i get around to putting my lg's in... i might get a new tunnel plate while everything is off to help with the in car temps since i won't be running cats... my lg's came with gaskets but i opted to get new gm mls gaskets instead

Regarding the noise level I have the same setup(LG Streets, Z06 Ti, O/R pipes though) and the car makes zero noise just cruising. Just accelerating normally above 2500 you can hear it a little bit and at WOT it does sound nice but pretty quiet. I wanted that stock level cruising and the setup delivers there but it's kind of disappointing at WOT. I wish it was way louder than it is. Can't have your cake and eat it too though.

Change your spark plugs when you do the headers (and the wires if you want). Your going to have to take out the spark plugs to get the headers in/out and there a pain. I spent more time getting the spark plug wires and plugs out of the engine then anything else. I went with the LG street headers with x-pipe/cats and it sounds really good I had corsa extreme exhaust installed prior to the headers and the sound changed alot just mainly deeper and louder at WOT. Still no drone until 100+ MPH. I recommend the LG, you get what you pay for and the kooks are for people who are cheap.

Our streets package includes the headers, mid pipes, and xpipe. It's a complete package.
LG is still back ordered on those. They should be in any day now.

I'm running Kooks 1 7/8 stepped to 2". I don't realy believe there is much difference from one brand to another among the top manufacturers.
