These should get you started. BTW see my signature.
And @ Irish Whiskey: I will put it against any similarly equipped C5 running LGs headers. Dyno numbers, or track numbers.

Look at my sig to see what kooks did for me.
No doubt, Lou sells some good headers. But the previous poster who recommended LGs, has installed KOOKS, was disappointed with the results, but has NOT had his car tuned after the header install, and is ready to go out and spend nearly 2 grand plus install, on LGs. 
Talk about throwing out the baby with the bath water. A decent tune, to include part throttle, etc, by a competent tuner is a lot cheaper.... But he doesn't want to do that.
BTW, I went from 298.8 RWHP/ 308.9 RWTQ (my car is an A4) with 2.73s to 323.8 RWHP/ 339.6 RWTQ after 3.42 gears and KOOKS headers, WITH CATS, and no tuning except for gear scaling.
Adding a Vararam (which adds little if anything on the dyno) and a Predator custom tune finally got me to the 327.9 RWHP/ 341.3 RWTQ you see in my signature.
A total gain of 29.1 RWHP/ 32.4 RWTQ. With cats. Can't forget the cats
The KOOKS rock, good luck with the install

The KOOKS rock, good luck with the install EB is faster at track due to TC I would bet (don't want to get into a Vararam vs. Trap argument do ya EB
)I'm hoping to increase my times now that I got H/C ported LS2 90 throttle body and Fast intake. Getting tune wednesday

Nice mods. And I see you had the car tuned by one of the best in the business.
Good luck with the heads and cam install.

I have the Kooks on my 02. You are going to like them. I had mine installed at LS1 Spped in Schaumburg,IL. They did a great job and fast. If you are too far away. Good luck! When you install your pipes make sure you have the right clearence over the axel. They bang on take off if you don't get them lined up.
