Anyone running Kooks headers?
Curious to know if you are getting any cat codes and whether there is a noticable performance upstroke.
Thx in advance for any posts.

Nice gain and no tuning required. I have eyed these headers for a while now. Just cant seem to get myself to want to install these as I know how much of a "not in a driveway" they are for an install.
