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.

Lou sells some good headers.
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 Last edited by '06 Quicksilver Z06; May 22, 2005 at 11:07 AM.

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.
