2009 CTS-V dyno tune
All runs were at 200-210* coolant temp and 100-110* IAT.
Did you retune after installation of the Kooks and are you running the Kooks into factory muffs?
Also, I'm assuming that you ran the Kook's x-pipe & Kook's pieces all the way back to the muffs?
If not, a big restriction on the '09's & up are the squished areas of the exhaust tubing where the factory hammered them for clearance for other items.
A 9" or a 9.5" lower will do a lot on top of what you have done.
What's do you have for a CAI?

Is that an auto (A6) or a stick (M6)?

Car's an auto, correct?
A CAI will help, but probably nothing out of the ordinary.
Did you retune after the Kooks were installed?
I have heard that the Corsa Sport muffs are good for about 16 RWHP and / or RWTQ on a bone stock '09 CTS-V.
If that was a stick, those #'s would be significantly higher, but so would the baseline.

This is a manual trans car too, our dyno is reluctant to giving glorious numbers on any car.
I have not done a muffler alone before and after but I would have a very hard time believing they improve it much at all.

And yes, I have a hard time believing that any muffler will add 16 RWHP too. but that's what I was told. Now that you mention it, that does seem pretty far fetched. I think that a tuner told me that, too.
You will start to see more from the headers and the CAI intake when you start making real boost. Getting the crank and blower pulley done with a snout upgrade and you will be making some good power!

What was the ambient temperature and the IAT's?
Would the car have done any better on higher octane fuel without a tune?
That was a great increase/improvement for only LPE pulley kit, CAI, & tune.
Exactly how much did yours pick up after the Kooks & Corsas?
If you had it over to do again, would you still do and / or recommend doing the Kooks & Corsas? How about the Kooks hooked up to the factory muffs?
Please post up the results of the heads &n cam, as I am closely following this thread.
Are you in a tuning / performance shop in LV?
With headers you could add timing but it would not make any more power in doing so.
Please let me know what it does with the heads and cam!!!!
