2010 Camaro SS L99 Kooks Headers and HP Cats install

We installed the Kooks headers and mid pipe in about 2 hours from start to finish. Wow! Seat of the pants dyno sure is impressive and the sound is nice.

[@rompn4x]

I have a full Kooks exhaust, Airaid cold air intake and had the car tuned. It made 407hp and 409 tq at the tires. Its a L99 auto as well.

[@TipsyLiquid]

rompn4x how much did it cost you to get the car tuned and what kind of tune was it?

[@moacircapelatti]

without touching the ecu ?

[@skinchen]

Damn it bill! Rev it!!!

[@reggier2343]

+Shannon Kinchen LOL

[@713soldja]

Lmao

[@sxmxmx1]

why doesn't this dude put on some more jewelry before he gets started

[@WackoKillerDan]

That "spear" is called a merge spike. It helps direct the flow of the exhaust more efficiently.

[@WackoKillerDan]

Lmao 6 years later…what are you waving at?

[@ParisTNDude]

The Kooks headers HF Cats will hook up to your stock X pipe and the back half of your stock axle backs with no problem. So, any after market Axle backs that will hook up to the stock X pipe will be OK. If you have an automatic L99, I recommend you buy an aftermarket X pipe and get rid of the resonator between the Cats and axle backs. The resonator really alters the good sound you're looking for and it's HEAVY. What you want is aftermarket Axle backs to hook to your system. Good luck!

[@Tranquiliz3]

Good video, I like how you showed what was going on with the install. Mean sound!

[@ohioken1]

Is it just me.... But that sounds like Ronald Reagan narrating this!

[@rmm2424]

Bob Ross got headers on his Camaro

[@benjaminvvv111]

Rev it bill

[@killerZR1]

The burns on my arm prove I did it hott!! Thanks for the video it helped a whole bunch

[@obednieto]

Loved the video,...bill probably didn't....but we do,thank you

[@killerZR1]

2010 l99, with a pypes cat back, I'm in love with the sound

[@ParisTNDude]

All of the "experts" say the 1 7/8 are the better choice for the 6.2 and that's what I used...huge difference in power. Good luck with your Camaro and let me know how it comes out.

[@ParisTNDude]

I did that shortly after the header install and you're right...the stocks sounded awful compared to the PowerFlo Pros I installed.Thanks for the comment.

[@audiomikej]

Rev it Bill! love it, good job, thanks for sharing.

[@SGMITCH919]

nice car i got the same Camaro SS/RS with the black and silver stripes, the only thing is mine is a LS3.

[@ParisTNDude]

We don't have emissions testing where I live, but others on the Camaro5 forum have passed their emissions testing even in California with the same set-up. It has catalytic converters and all systems are connected as from the factory. I think the Kooks has an emmissions certification on this product, but not sure.

[@philritter21]

Thank you for posting this video. I was hoping this was something that could be done with a car lift and a little bit of tinkering experience. But I think Ill save it for the experts!

[@ParisTNDude]

Strange...I didn't get a code for at least a month or so and then received the typical rear oxygen sensor code. The reason it does that, is that long tube headers place the rear oxygen sensors further away from the exhaust ports and the exhaust is cooler at that point. The rear sensors have no interaction with the ECU unit and whey you get a dyno tune, they turn that feed back out and it never reappears. You need a tune to get the most out of long tube headers anyway, so it's no big deal.

[@ryu10000]

Great video! Thanks for posting this.

[@iannamico]

nothing worse than being a mechanic and having some jabroni over your shoulder the whole time asking stupid questions.

[@jerryberry2578]

Thanks...there's no better sound in all the world than a small block Chevy at 3500 - 4500 rpm. Ford's modular V8 sounds good as well...just doesn't run like a Chevy.

[@ParisTNDude]

It wasn't absolutely necessary, but for most (not mine) it would throw a code for rear 02 sensors and a tune turns it off. Also, the headers without a tune will not maximize the power. With no other mods and a tune, the butt dyno alone told you you had gobs of power. If you do headers also do a tune, even if it's an email tune from like Jannetty racing...I did that and it was great.

[@ParisTNDude]

No, didn't have to disconnect the steering shaft. It was close to a rubber or plastic part but passed without a problem. Thanks for the question.

[@ParisTNDude]

Incidentally, I traded this car for a 2012 LS3 stick shift car. Before it went to the dealer, I removed all the mods that I could including the headers and HF cats, axle back exhaust etc. I did that work myself in my garage on jack stands and it was not difficult at all. You have to get both front and rear of the car as high as you can on jackstands otherwise you can't slide the headers from the bottom. I'm going to install those headers on my 2012 myself the same way I took the others off!

[@buddyrebel_Garcia]

Good Job Bill

[@papabearcamaro]

Another nice video sir. Very well done. I also have the Kooks headers going into their high-flow cats than into the Borla S-Type cat backs. Love the Kooks quality and sound. Just as good as the American Racing headers for less money. Keep the great vids coming!

[@djkaneck1]

Wow you made it look so easy. I’m doing it today!

[@ParisTNDude]

Thanks for the comment. Incidentally, I traded that Camaro for an LS3 Camaro SS with 6 speed manual. Just this weekend, I installed these headers on the new car...strange, they sound different, but still nice. These headers make lots of horsepower that you can feel in your first ride afterward. Going to install my Jannetty tune today which should really wake this new Camaro up as it did on the l99.

[@ParisTNDude]

I had the l99 running really decent with a dyno tune, headers, full exhaust and a great CAI....it ran 12.4s @ 112...that's C6 Corvette territory. Anyway, first runs with the LS3 weren't that impressive...as I expected. Now I have all the mods that were on my l99 so we'll see. Thinking of heading to test and tune thursday in Memphis.

[@tylerdelavan772]

I would go lightly on the antiseize. The header bolts tend to back out

[@WhoIsThisGodPersonAnyway]

I couldn't find a point where it showed the muffler. It sounds straight-pipped through the muffler with the resonator obviously in-tact (good idea on the L99 if cylinder deactivation isn't tuned out). So, was the exhaust changed past the resonator?

[@killerZR1]

Btw the driver side high o2 sensor was the hardest to remove, even with the o2 sensor socket

[@ParisTNDude]

@robojn06 No problems with the Janetty tune...if you buy the SCT tuner from Janetty he will email you a tune custom made for your car. You just simply tell him your mods and he'll set you up. When I initially did my tune, it was like adding a supercharger....not really but it flat woke the car up. Do it...you won't be sorry.

[@RICHILITO1]

REV IT BILL! Nice car

[@ParisTNDude]

The headers? About $1K with oxygen sensor extension cable and HF cats, shipped.

[@hankrearden7215]

I have the exact same car right down to the color.

[@yungterv198]

DAMN IT BILL

[@ragzelaznog88]

Thanks..I will

[@ParisTNDude]

Agreed, I usually remove any jewelry when I'm doing mechanical work...very dangerous, isn't it?

[@ragzelaznog88]

Thanks..after watching this I'm going to go wit kooks as week for my 2012 Camaro SS..did u go with 1 3/4 cats or 1 7/8 cats?

[@DuhKoDuhCantrell]

When you say Janetty, who is that? the free tune sounds like a good deal!

[@ParisTNDude]

@DuhKoDuhCantrell Jannetty is one of the better LS engine tuners in the country. Google it and you'll find him. He sells Camaro/Corvette mod parts as well and he has close to the best prices. When you install long tube headers, you won't get the max power until you get an ECU tune. You buy the headers and an SCT tuner from Jannetty and he will email you a custom tune for your car. He dynos about every possible combination of mod parts and will actually give you a better tune than dyno tunes.

[@kj9217]

random question......... Are you the guy that does Raging Bull Replicas? sound exactly alike

[@TheCitySirs]

if ya would of install a new bigger aftermarket catback i would of sound wayyyy better but still a beast

[@13slot28]

very nice.. in my opinion u need a Magnaflow Cat back system to finish the job :) but awsome vid :)

[@xbryan666x]

Sounds awesome. I plan on getting the Kooks headers and a Borla S-Type exhaust. Did you need to get a tune after the headers were installed?

[@kilik92]

ParisTNDude . did you get increased performance with this? how many hp?

[@CupofTea3]

These are long tubes right?

[@robojn06]

Have you had any problems with your email tune from Jannetty? Thinking about going that route for my tune. Would appreciate any feedback.

[@siliconcpu]

Awesome sound! I just got a 2015 Camaro SS L99 and put SLP Loudmouth I exhaust on it. I'm about to get the Rotofab cold air intake & Kooks long tube headers installed w/HP cats + dyno tune. Is the resonator installed on this vehicle at the end of the video? It looks like it's still there? Did you notice a big sound difference when taking it off?

[@Dcook18]

So if you get the kooks headers u need a x pipe?or could you just get kooks headers with cats and put bor atak catback? Sorry i am new to this. Im hoping to get borla atak with kooks long tube headers with cats. Thanks for help

[@ragzelaznog88]

Did u have to tune ur car after installing those headers?

[@ParisTNDude]

Corsas are awesomely good axle backs that should make your Camaro sound really good. It depends on the model....my last Vette had Corsa touring and they were perfect...not too loud or too soft. Headers will give you car a more aggressive, deeper, race car sound....do it!

[@bam40x]

I have the same color scheme how much?

[@Lucicsux]

How much horsepower and torque would those headers add?

[@edwingarcia9583]

what did you do with the first set of sensors

[@Joey-ri3vs]

Have you had any problems with the Kooks long tube headers just wanted too know I plan on buying some . I drive my 2ss a lot just wanted to know how the car is running

[@Joey-ri3vs]

on I have a 2015 2ss

[@ParisTNDude]

Glad we could help. What did you put them on?

[@Macndahat1]

Did you get any check engine codes?

[@gutterratjp]

Do you still have the car?

[@ParisTNDude]

@xbryan666x The headers alone made a heck of an improvement, but when I got an email tune from Janetty, it flat woke the car up. If you buy your headers from Janetty, you can get a free email tune and trust me, this guy is the best and well worth buying from him. Good luck.

[@kevinkotchevar2339]

Spend an additional 110.00 and put A R P header studs in with 12 point nuts stainless steel makes it even easier

[@gerardomarquez8451]

What website you buy from ?

[@The2008ktm450]

does he keep calling different parts of the car a "hummer" ?

[@doncruize9184]

Did you eventually take your resonator off?

[@hotstreetcar]

Any starter issues with the long tubes

[@moacircapelatti]

how many hp increases these collectors in camaro L99 ?

[@moacircapelatti]

what is the kooks model for the camaro v8 l99

[@eaglebaize]

So jealous :D

[@Dcook18]

Does it pas

[@JBWHITEGT]

should remove those factory crap mufflers for something else... or just completely remove since you kept cats on.

[@rayray3521]

you can hear it now by golly!

[@TheWildBoySteveO]

My check engine turned on is that normal?

[@skinchen]

Esteban Pena check your tune

[@sharpoutdoors3368]

+Esteban Pena totally normal sincd your cats are not there.

[@jyreece]

Have to get it tuned

[@ParisTNDude]

@bobsecretagent They will fit the 2011.

[@LGmarge]

Those blankets are dirty as fuck. Guaranteed scratches

[@K9JESS]

What was the cost of this install?

[@Dcook18]

Does it pass emissions

[@reggier2343]

man take off your jewelry.

[@ParisTNDude]

@1vdn992 I can afford Bill's but not your's ..... lol
