i have an 03 cobra and the first thing i did was put on the magnaflow cat backs and the off road x-pipe. now i wanna put some headers on and im not realy sure which ones to get or even if any can fit the x-pipe that i have on. any help would be much appreciated guys.

The KOOKS ones are supposed to be the best, but I don't think they make a shorty style header to fit your current X-pipe. I know FMS makes a shorty header, but it might be better to just do the long tube KOOKS with their X-pipe.

yea that's what I'm thinking... i was just trying to figure out if there was a header that fit my x-pipe but always figured i would have to change pipes. thanks for ur help. by the way does anyone here really know what headers have provided the best performance and horsepower for the 03-04 cobras??

Check into Accufab as well, I had a set on my 96 for a while and they were nice for the money. I have installed just about every brand for the 4.6's and they seemed to be closest to the kooks in quality.

thanks i will for sure look into that. does anyone know the kind of power i will get from like top of the lines like kooks. i have a 03 KB cobra with 590rwhp. i want hte headers for the sound but am curious about the HP gains also

I would assume at least 30 rwhp, I picked up 18 rwhp on my 96 with the Accufabs with only a N/A little 2 valve a few years ago.
