When you first installed them did
You let the car adjust to the
New flow and take it
Slow for the 50 to 100 miles or did you get on it right
Out of the box
To see what they could do

Have you talked to the guys at Kooks? They're usually really friendly and have an extremely knowledgeable staff... just a thought to see if they've got any ideas-couldn't hurt right?

I also have the Kook's long tubes with highflow cats on my R/T with Flowmaster American Thunder exhaust. I Still have my engine light on as well. Here was my thread

http://www.challengertalk.com/forums/f18/o2-spacers-then-interesting-trouble-code-your-thoughts-52019/

To sum it up though the only conclusion I could come to was that I need to get a tune and the catted spacers. Before I do anymore though I am trying to ditch the cats to get more sound. So to get a tune before that would be a waste and well using the catted spacers before even that well you get the idea lol.

I don't want to hijack your tread and don't want to say anything bad about kooks but have you thought about solo's new hf cats. I and a few other members have them and we have no cel trouble. I am the first tester and have almost 1000 miles on mine and the first set I tested had over 2000 miles on them with no trouble. It's just a thought I'm just trying to help.

The solo's wont fit long tube headers.The location of the cats on long tubes are a lot further down compared to shorties,being located so far from the stock location alters the temperature and flow of the exhaust tripping all kinds of 02 sensor codes.

Hey Scott,
Not tryingto burst your bubble but there was another thread on here about using those 02 simulator mini cats and they didn't work for several people, I think they did for one.

They might work on the Charger, K. Scott's got an '06 and the pre-'08 ECM's seem to be a bit more forgiving.
