Finally installed the Kooks

[AMCRambler]

I picked up a used set of Kooks long tube headers and high flow cats for my GTO about 6 months ago. I got them re-coated with Jet Hot and finally got around to installing them this weekend.
For those of you who know, putting them on these cars is a pain in the ass. Have to drop the steering rack to get enough room. So far about 10 hours of work, going slow and making sure I didn't break anything.
LT's are on and steering rack is bolted back up. Waiting for two new upstream O2 sensors from Rock Auto since one of the originals was cross threaded and did not come out in one piece.
Excuse the dirty engine bay, I haven't had a chance to detail it yet.

Update:
Still to do:
-Tune

Everything is in and hooked up. How does it sound?

A GTO would be a fun car in the garage. Sigh... Too many cars and not enough room.

 

[Aharami]

that's a sweet sound!

 

[alkalinetaupehat]

Dude that's wicked sick! Favorited that video for when I'm making an exhaust for my V8 swap.

 

[manimal]

sweet sound! Your goat really sings!

 

[KentState]

That's a very familiar sound

 

[AdamK47]

Sounds good. Clean that thing up!

Mine doesn't see much dirt. Sits in the garage in the winter and on any rainy days.

Here's mine last year with Kooks 1-7/8", 3" SpinTech, and a ginormous cam.

Damn I want one of these cars more than ever..

 

[DaTT]

Sounds great. Throw some lumpy cams in there now.

I wish it was worth the money to put headers on my car.

 

[Kadarin]

Reminds me of how mine sounded with the JBA shorties (I had to go CA-legal) and the Corsa x-pipe exhaust. Very nice, and congrats!

These engines actually work better when you use one cam.

Obviously not open headers like the title says, but sounds amazing. No idea what the guy is running.


What actual open headers sound like. Turn the volume down on your PC before watching this one. The neighbors must love this guy:

Thanks for the props.

I think this is probably as far as I'll go with it for now. Cam means taking the valve train apart and I'm not going there just yet. I'll probably swap out the home made over the rad intake for a professional one, do the upgraded IAT sensor and then get it dyno tuned to see what it netted me. Horsepower is addictive though.

Wife keeps me from spending all the dough on it though, thank goodness. If I wasn't married I'd be broke with 15 grand into that car. Blower, cam, cat back, catless mids, the long tubes, etc. And I'd be shopping for an iron block to build a stroker. Hell there's a Maggie mp112 for sale on *********** for $4k I can't stop eyeballing right now.

Pariah if I was guessing I'd say that first vid is probably cutouts. Second vid is definitely open headers. Ridiculously loud. At 2000 rpm's it's causing hearing loss, lol. Had a Chevy Nova go by me once with open header 3 lanes away and had to hold my fingers in my ears. I swear they were bleeding.

This is what my Kooks sounds like with exhaust. I'm thinking about electronic cutouts this summer.

Haha nice. Sounds nasty! Spin tech made a 3 inch side exit?

That is not the sound of your grandfather's Cadillac hehe. Now is that the one that got the blower put on it?

Yep

What did you do with the rear bumper insert? I'm thinking that would look funny with the cutouts for tail pipes but no pipes.

Also, didn't your motor drop a valve or something after the shop put your new cam in? I remember you saying they were going to make it right for you. Is it back to good now?

It comes with a blower from the factory. Depending on which end of the car you are at, you either hear the blower or the exhaust.

very nice but a lot of work

It wasn't that. They did a simple catch can install incorrectly that sucked all of the oil out from the block. The crankcase clean air source hose was connected to the crankcase vapor source with a T-fitting and then the outlet went into the intake manifold. They gave me a new shortblock.

I want to get some upgrades this year. Haven't decided what to get.

Damn. That's an expensive mistake.

So they put the new motor in for you and everything? Good shop. That's honestly owning up to your mistakes. I bet the guy that did the install got his ass chewed good for that one.

What size tires are you running? Back when I had mine, 275 was the most people did.
