Something isn't right, the SW should be a direct swap with the slip connections. I can't speak for the Kooks though.
This is what I've heard as well. Curious about this if it'll be more trouble than what I'm expecting if they don't match up.

I have SW longtubes and SW mid-pipe with high flow cats. The cat-back is a custom unit Dave tigged up for me.

Tedd Britt Ford Chantilly installed my headers and mid-pipe. Don't remember exactly what they charged but it was on par with what other folks were paying at the time (this was back in late 2010).
Love the long tubes and mid pipe, ditched the cat back because it was too loud (I had the quiet version of the two options offered in 2010). I now have a custom cat-back with a magnaflow muffler and resonator. Sounds killer and isn't too loud.
I'll have to give them a call and see what they say. I didn't even think to ask if a dealership could do this. Thanks for this tip.
