Got mine from e bay brand new last year obx system, with CAI, and a tune 338 rwhp gain, so not bad for headers for this price. Comes without o2 sensor extensions, but they cost like 50-60$ so still can be under 750 if doing install yourself.

wow a 338rwhp gain with these headers and x pipe? lol i know your talking you made 338rwhp with this setup and well you paid 750 for it cause most systems like kooks and Lg headers are making around the 350 range with the same setup

The OP was asking about mods for his 03 Auto coupe, I have z51 a4 so I believe he would have similar gains as I did if he chose to do this mod. 6 speed makes 10-15 rwhp more to begin with so M6 will make about 350 that is correct.
Wow fellas, I never expected a response like this! Seems the consensus is cai, exhaust and tune. I'm gonna get started. If I can get all that, it will be great. Thanks guys.
