I just got my car back from Livernois Motorsports yesterday and I had them put on my Kooks Long Tube Headers 6905-5.7CC. They did a terrific job as well they Dynoed the Challenger RT as well. Heres some pics of the headers and my car tell me what you think.

Nice! I'd consider dropping the car a bit to get rid of the large gaps the R/T's have at the wheel wells, but that's just my two bits. Great looking ride!

Pretty much an across the board 30rwhp and 30rwtq. More than I expected. Any issues with throwing codes once installed?

No i have not had any problems with codes throwing and i actually had the car back for a week and put about 250 miles on it so everything is running really smooth which i have heard of people putting these headers on their challenger and they had problems with throwing codes but i havnt yet knock on wood lol

Good to know on the codes... and like the previous said, if you can post a video I'd love to hear it. Looking at those pictures and the results you got I'm thinking about moving this item up on my list :)

Did they have to re-tune the car or was it a bolt-on and go?

They had to tune the car after the install the process to install the headers took a while it's a pretty big job. Also ill try to post a video online i have to borrow a cam corder to take a video but it does sound really good like a Challenger should sound like. Plus a good thing about the headers is that it does come with a lifetime warranty as well as 2 years on the cats.

Is it a 3 inch system, or 2 1/2? Is it headers, mids with cats, and catbacks all by Kooks? And if you would please, do you get that annoying drone while driving? I think Kooks has the most beautiful pipes etc., But I bought my Challenger for comfort as well as speed, I couldn't imagine driving it with a constant rumble inside. It's just too nice of a car for that. And THANKS for the great post!!!

Really nice. May I ask why you choose Kooks long tube headers? I read on another thread long tube headers aren't necessarily better. They really shine at high RPM and that short tube headers do just fine at low RPM. Since my R/T is my only car, I try to keep the RPM's low when going from red light to red light. :) Did I misunderstand something?
