Has anyone installed the kooks headers alone? Are you happy with the gains and sound? Any clips?

I will soon. Mine should be here tomorrow.

Thanks I'd love to see the results

I am interested also to know. I was going to go this route and wanting to hear what you think. Thanks

Refer to http://www.cadillacforums.com/forums/cadillac-cts-v-series-forum-2009/182708-kooks-headers-oem-muffs.html for my brief description of what the car sounds like.

Aceofblitz,

Do you have an after market pulley installed? Sorry if I missed a previous thread of your mods.

Yea, 9" pulley, Throttle body, 160 Tstat, Heat Exchanger, W4M full CAI, W4M Tune, and Kooks Headers. Stock pull was 454rwhp, after mods its 537rwhp. Quite a good jump IMO.
Ordered a 9.5 pulley and I should iron things out with a custom tune soon. so far W4M's tune is doing quite well although it wasn't made with kooks headers in mind.

Thanks for the info. If I can remain "good" I'm hoping Santa will have some of those items under our tree for me next month. A nice increase in rwhp and you didn't have to go into the motor. What do you anticipate gaining by the 9.5" and a tune for all the mods?

I don't like guessing numbers.. my main goal is to be faster than a certain car with 2 doors, with my mods i'm sure i'm faster than that "certain car" if it were stock (I tested). The extra mods are just more for a little guarantee heh.
But if you insist on a number.. how does 556 rwhp sound? :P

Which Throttle body and by whom ? And what size ? I have 9.55 coming

All my parts are Wait4Me Performance parts. 90mm.

Paschal Performance,

Were you able to install them yet?

Should install everything next week.
