1 7/8 kooks installed :D Finaly got these on.
Gotta say best mod so far as far as feeling a power gain.
The car rips now, its amazing how hard it puts you back in your seat.
I cant beat it to much cause it does need to get re-tuned. I can feel some dead spots at certain RPMs , and im not sure if its running to lean so I only opened it upalittle.
Just orderd my hendrix clutch kit tonight so after that is installed I'll retune.
Im running the kooks cat connectors along with a x-pipe and OBX mufflers that stay pretty quiet untill I get on it, which I like. And I think Im going to buy a electronic cutout down the road but for daily driving I dont like it to loud. I barly have any drone at all..
The only thing Im not happy about it how close the headers are to the steering rod...I think i can feel it touch on hard right hand turns...
My only thought is my motor mount isnt fully doing its job anymore ?
.. But im going to look into it more another day..
Im amazed at how tight everything is next to the connectors, but everything there seems ok.
I also need to upgrade the clamps that connect to the cat connectors to the stock catback, they are cheap *** autozone ones that I dont ,kooks didnt come with them like I thought they did. .
here are some pics, and a very poor video I took tonight. But its got good sound
Was anyone elses 1 7/8 set this close ?? (its about a 1/8 inch away from the pipe ) ??
I honestly dont like how close it is but ill figure something out..
heres the Video , volume up. My cam has a slight chop to it, the tune mellowed it out alot compared to when I first got it.

Wow those 1 7/8s look really big,.
Here are some pics of my 1 3/4. I've seen some people with the same size as me that came a lot closer to the steering shaft, I think one guy even dented his headers a little to make room.

Congrats on the headers! How much more engine noise do you hear? Much valve train noise? Not a real fan of how close the steering rod is to the headers, I guess a small love tap won't hurt too much.

Got the 1 3/4 Kooks installed today. I have a good 1/2in between the headers and the steering shaft so it must be either the 1 7/8 or a tolerance issue with yours...
My issues were:
O2 extension cables were incorrect. For some reason my CTS-V has the harness and O2's with only one key where as the vettes have two. So the extensions they sent were for a vette type O2 sensors. Did'nt need them anyway the harness has enough room...
The wiring harness that runs near the oil filter was touching the headers. I had to heat shield it as there was not enough slack to move it out of harms way.
otherwise it was a easy install and they sound awesome with the Corsa catback. Absolutely no drone. I believe it is even quieter than the stock manifolds and cats inside the cabin.
Great mod, the car loves the longtubes just like every other LS based vehicle I have owned.....

After looking more into it, I think the reason it hits is cause my motor mounts are shot and sagging...
Ive got a set of creative steel ones waiting to be installed so i hope it helps.
If that doesnt work im just going to tap it with a hammer a bit..
And the other thing I wasnt very happy about is it didnt come with the clamps that connect the cats to the stock exhaust .
Did yours?
For 1300 i thought that would be included.
i bought a cheap autozone set but honestly they are kind of ugly and cheap looking.....

Oh ya, the motor mounts being shot would move them. Forgot about that..
My car had a corsa catback when I got it so my catted midpipes just used the existing corsa clamps.
You are right, they should come with a set of clamps anyway for the money.
Been raining here (finally, we need it) so I have not had a chance to log and tune it yet since it gets sideways quick when its slick. But I did weld in a extra bung for my wideband before I installed them....
