Default OEM Exhaust Header Gasket??

Ok how hard is it to change out the OEM exhaust header gasket? Is it time consuming? Do I need to remove the entire exhaust?

How much is the gasket?

Which gasket? There is the donut gasket between the header and the cat. There is also the gasket between the head and header. Both gaskets are easy to change and just require removing some bolts. And no, you don't have to drop the entire exhaust system.

^^Like he said, very easy. Matter of minutes. On the header-to-cat donut gasket, it's basically two bolts with springs on the other side that you can soak overnight in PB blaster and slide off in the morning. The exhaust system flexes enough to allow you to slide the gasket in there.

oh man you think replace gasket is that simple? just some bolts? you know how important is it to replace the gastket properly?

first...all exhaust gasket must be soak in water at least 6hrs before put in(not including metal gasket which not recommend to use)

second....all exhaust ports and gasket must have some gasket fluid to seal up properly (can be buy from kragen or autozone, ask them for fluid that use with gasket to prevent air leaking)

third....the gasket worth to replace OEM is performance gasket that is thin and acts as preventing excess amount of heat from the head to header (this part only apply to head to header, not exhaust flanges gasket)

on and on....

I've never heard of soaking any of the gaskets that go onto the exhaust manifold. The one to the head is a metal gasket and the one to the cat is a lead filled one. Secondly, I've also never heard of people using any sort of gasket fluid/selant on the gaskets. As long as the gasket is good and the bolts are properly torqued down, I don't think you need to worry about any leaking.

soaking them in water?? just replace em, there metal gaskets, soaking them is pointless, gasket between the head and exhaust manifold never really goes bad so probably no need to replace, exhause "donuts" between cat and manifold tend to go bad. Just spray them with penetrant and let em soak.

I did not replace any of my gaskets when I put on my header/cat/exhaust. If something starts to leak, which I doubt it will, I'll do something about it. Until then there is no need to worry.

It doesn't do anything - none of the OEM gaskets will absorb water. I honestly have no idea where yeegsr obtained any of the information in his post, but none of it is accurate (at least not with respect to a typical Honda/Acura exhaust system).

Yeah, I think he may be referring to cork/other expansive gaskets.

I just had my cat-bpipe gasket replaced. It wasn't that bad, just unbolt and take out the old one and place the new one(It was done in a shop with a lift). The heat from the exhaust will melt the new old and seals it permanently assumely that you are not going to unbolt and remove it again. the Reason I had a new gasket cause I just put the OEM exhaust back on. Now the cars Driving strong and fine.

man did i say not including metal gaskets...jesus...others composed gasket when soak in water before use will help sealing much better for ensure of no leak will happens...
cumon man...it's cummon sense that stainless steel gasket can't absorb water why ask why

if any of you haven't hear about this NOW you do....
someone mention OEM's gasket....i believe OEM gasket is a stainless steel...so dont soak it.....dann i mention earlier already...

i boil my gasket and see it bubbling...when bublles appear meaning the gasket is empty inside...heat up the gasket with water help the gasket's material to seal up its empty space inside...so when put on the flange or head to header it WONT' have a chance to leak air out...

do watever you guy like...appreciate me if you know the benifit of it...

judging by this and the thread you participated in about the cat, i can tell you have no business working on cars. i hope yours is the only one that you ruin, and that you don't "help" out your friends too much.

you dont need to do all that junk he said. the only thing that might make this difficult is if the gasket has already been replaced, with one of the carbon ones from autozone or whatever, and you need to remove the stuck-on pieces off of the head.
other than that, it's simple as said before. remove the bolts, remove the old gasket, and replace.
