[@CashMullen-ng4sr]

I recently purchased a new '23 C8 Z51 and I saw that Kooks headers actually lose HP compared to the stock exhaust manifolds due to the restrictive 2.5" flange outlet. The better choices are ARH and aFe with 2.875" & 2.75" outlets respectively. So it looks like ARH for the win!

[@Kracka21C8]

Agreed on ARH & aFe being the better choices vs. Kooks on the C8. I personally run aFe headers + Corsa cats.

[@Jaydayallday]

How’s the tone of the sound ? I love the sound that it’s kicking in this video. I already have a borla extreme exhaust and want to do headers and cats

Is that headers only with stock exhaust ?

@@speedsociety Just installed Kooks headers to my 2023 c8 with akrapovic exhaust. It sounds like a BEAST but I need to get it tuned (rough ride). Need to get it tuned but no software 👎🏽

if you have performance exhaust valves from the factory do they still work?

[@C8Z51Scott]

Sounds great. What HP and TQ increase?

[@vhayne91777]

Sounds great. :) I may be wrong, but I believe the increase in volume is coming from the new "higher flow" cats, not really the headers. Headers help a bit though.

[@DaveGee0]

I believe you are correct. If you look at the stock tube headers compared to any aftermarket header there is very little difference. The Hi-Flow Cats and the exhaust system is where the real sound increase is coming from. I have a new C8 and I have on order the same Kooks Cats but a Borla Atak exhaust system on the way. I don't see any need to swap out the stock tube headers. These guys do it because they get them for free for the advertising. My system will sound just as bad-ass.... Without swapping out the stock headers.

[@vhayne91777]

@@DaveGee0 Currently I'm running my C8 with fabspeed cat bypass pipes, and stock headers and stock exhaust (z51). It's loud AF when full throttle. But still quiet at idle speeds. And very quiet in Tour mode. I plan to get an exhaust system, although not sure which since the vast majority of videos are only with exhaust (stock cats). I want an exotic/higher pitch sound, kindof like my C7Z06.

[@ryants1]

@@vhayne91777 any thrown codes with the cat bypass? My c8 is coming soon and it has the z51 exhaust. At some point I know I’ll want a louder exhaust. Also, did you get new exhaust since then?

[@vhayne91777]

@@ryants1 Yes, unfortunately even with the mini-cats that Fabspeed sells. No biggie to me though.

[@vhayne91777]

@@ryants1 I'm sorry, I forgot to answer your other question. No, I haven't purchased a new exhaust yet. I want to, just had other things to deal with. Such is life... :)

[@gorebloodzz9316]

Hey so which parts do we need to buy exactly for this build?

[@danieldelgado3008]

Is this with the factory cat back exhaust??

[@domenicp196]

Do you need to tune the car after header and cat install

What exhaust did you use with kooks headers

[@MH-kv2hj]

All smiles! Nice video

[@MaineFitClub]

Sounds great. Fantastic!!!

[@steves3830]

@speedsociety to be clear this is stock muffler with kooks headers?

[@chandlermccall2246]

I'd love to have that car in my driveway. Talk about a dream come true🤤

[@Paff805]

I'm doing a header/sport cat combo with 2m fabrication on my C8. Your combo with kooks sound amazing. Any experience with 2m? I haven't seen many reviews.

[@bosslife3663]

May I ask... How much is this setup?

[@Pourings]

Is the AUDIO coming from inside the cabin or from the engine bay itself?

[@amiller2121]

I think it was coming from the outside (mic above exhaust tips). It's a little deceptive if you ask me.

[@dereksteneman9657]

Damn that sounds good

[@supergoat06]

is there some gasket leakage going on there? noticed quite a bit of smoke in the engine bay.

[@speedsociety]

New headers, so they were burning off some of the coating from manufacturing. Happens with every new set of headers!

[@supergoat06]

@@speedsociety kind of figured, seemed a bit excessive but I guess being that the engine bay is visible its more noticeable then one would see with a front engine vehicle :P

[@yujiechen239]

Do you need ceramic coating?

[@louie111887]

are these california smog legal ?

[@PaulJersey]

Wow! Awesome!

[@MasterKenG1]

Is this setup with the stock exhaust/performance factory exhaust?

[@DailyElectrician]

think they said fab speed exhaust

[@mattantunez]

Its the stock exhaust. you can see when they film the rear of the vehicle in the beginning.

[@Salvi_J2]

2:26 fab speed

[@justinkarim5976]

The engine bay @4:35 🔥. That can't be good.

Brand new headers have a coating that burns off in the first drive/startup as they heat up, totally normal

Quick correction, Kooks cats are actually 400-cell. GESi G-Sport GEN2 S-Wound cores to be exact. Same as Corsa's C8 high-flow sport cats.

[@yujiechen239]

I ordered the kooks headers with the corsa high flow cats. You think this setup would be a problem?

[@yujiechen239]

Also did you get the headers coating?

[@Kracka21C8]

@@yujiechen239 No sir, they'll be a good pairing. Both use the same GESi core. I personally run the Corsa cats too, 2+ years and no CEL or issues!

It's really a shame that kooks headers sound so good but consistently deliver negative performance gains on multiple dynos from different companies . They were my go to for my c7, hopefully they get it figured out by the time my 2023 comes in.
