Before i get my ZZP Header/DP installed i wanted to make sure i didnt need to buy an extra header gasket since the combo doesnt come with one...Ive read that you could use the stock header gasket but im not sure how that would work, since wouldnt the stock header and my new 1.5" ZZP header be different sizes?

do you guys recommend just keeping the stock one on or buying a new one? How much would it cost from a dealership?

 

I bought another gasket just incase the other one is messed up, the gasket it 14 bucks from the gm dealership but honestly since i already have the headers installed i dont think ill ever install the new gasket. The part number is Gm#9230949 Have them check this just incase

 

thanks for the info, ill probably do the same thing just in case. but as far as the size of the stock gasket, it will match up with the new headers no problem?

 

All mechanics will replace when they replace no matter what. You break the seal when you open it. Buy a new one, its only 3 dollars at the dealership. Stop being a cheap noob.

 

what are you talking about? and how exactly am i being a "cheap noob"??

i asked whether the new headers would fit with the stock header gasket since ZZP doesnt provide one and if it didnt, why would i wait until i get everything installed ot be told to go to the dealship and have to get a new gasket..Id like to be prepared.

And please dont call me a cheap noob...Im 17 years old and paying for everything that goes into my car, payments, insurance, and any mods i have including the ZZP header/DP which cost me $450, the cat back im buying in two weeks for $350.

 

You want a prize? I affording alot more then you, and im a cheap noob too. I was referring to you asking to use the same gasket, calm down. Look at it this way about the gasket, used condom, or new condom? You choose.

 

okay... and like i said, instead of finding out i need a new gasket in the middle of installing the thing, and having to rush to the dealership, id like to be prepared for something i might need to buy extra before hand.

 

Oki Now you know

 

Yes I do...

I really didnt care if i needed to buy a new gasket for it or not and whether it cost $10 or $75, i wouldve got it either way...No where in either of my posts did i say i wouldnt dish out the money for a gasket if someone recommended i got one which made me get a little po'd at your post. It was a simple question just so i knew i could goto the installation prepared and not have to worry about any confusion half way through it,

 

WELL im sorry

forgive me ?

 

 

Just as a heads up, I always replaced gaskets, screws all that fun stuff. Just because stock stuff once removed seems like its crap, I mean its not always the case, but after so many mods and breaking stock bolts on friends cars, I started with always replacing new peices. My advice to you! and good luck with the install.

 

The stock exhaust mani gasket is MLS, and its 100% re-usable unless you damage it. They are excellent gaskets and work flawlessly as long as you torque the manifold down correctly, which is necessary for any flange gasket to seal.

They are cheap though, and having a spare just in case you do damage the stock one isn't the worst idea, but I don't think you will have a problem, I didn't.

The gasket is more than fine as far as port clearance on the header. If anything, the ports in the head are the smallest point.

 

before you start talking **** to someone, make sure you know what you're talking about.

the manifold gasket is not a cheap "paper" style gasket, it's made of copper (i think) and can be reused unless it's damaged.

 

ASk a GM mechanic, thanks.

 

Its not copper, its 'MLS' or Multi Layer Steel, made of a spring steel alloy, similar to a head gasket construction but more simple.

 

learn from experience. thanks.

and btw, are you talking about that same mechanic that tells you that you need a new air filter? even though you just replaced it? or the one that says your new oil is dirty? or that you need new heater hoses? the ones that are pretty much trained to sell you crap you don't need? yea, thought so.

as i said. unless the gasket is damaged, you can re-use it. and stop being a dick to someone just because you don't know the answer to his question.

 

So do you assume that every GM mechanic has actual knowledge and experience with this area? I don't doubt that some do, but I have met several ASE cert'd GM techs that I wouldn't trust to change my oil, much less actually value thier opinion on parts.

 

there ya go. i wasn't positive what it was. now i know

 

No im talking about a guy in my car club, who works for Ac Delco now. Thanks, and I do know from experience, hence why I replaced mine. They will leak once factory seal is broken. Nice try talking down to me kid, I walk into dealerships and what I want gets done to my car. I don't get the run around half the guys in our dealerships we go to out here are friends and in car clubs with us. Now I see why you get lied to.

 

Not if installed and torqued correctly. Speaking from experience here.

 

first off, i'm not a kid. 2nd off, you're still wrong. just because it's what you want, doesn't mean it's the way. but you're too stubborn to see that, and a dick to boot. so that being said, you're right. i don't now what i'm talking about.

 

Well said.

 

I have torque sheets for all parts got them the day my friends snapped his exhaust bolts. And I use em anytime I ever mod. So I am well aware.

And Im glad you realize.

 

well now you're also aware that if the manifold gasket is not damaged, you don't have to replace it.

other gaskets in the exhaust i would def. replace though. like manifold to downpipe, and downpipe to catback
