The thing that made me choose ARH over kooks in because Kooks uses somewhat of a slip fit design, where as ARH is 1 solid piece so you won't have to worry about leaks!

Same set I got on my cobra:

rygi23 that really helped me a lot more than you can imagine, you definitely answered a lot of my questions with that one I really appreciate it. Now I have just got to figure out what kind of sound im looking for

 

what kind of performance gain did you get with that set you got on your car

 

I have not got my car on a dyno yet but I have been told with these Lt's, catted x and catback it is good for about 35hp. I have deff noticed a increase in performance, especially the top end. What good about these headers are they are stainless steel so they will never rust out.

...one of the sexiest sounds I have ever heard. A buddy of mine has that setup. Too bad he lives about 40 minutes away or I'd get a clip of it.
