How To Replace An Exhaust Manifold

Having and exhaust manifold replaced can be expensive. Doing it yourself is not as hard as it looks, and it can save you a lot of money. Watch as we do it on a 2000 Honda Civic Si.

Anyone know why the bottom of the manifold does not have a gasket? I mean the part that joins the bottom of the manifold to the top of the front pipe.

What vehicle are you referring to?

i just bought a 2000 jetta 2.0. It make a bad rattle/grinding sound when stepping on the accelerator hard. ive had mechanics look at it and they said no exhaust leaks from under the car. do you think its the exhaust manifold or the flanges?

I have no idea without having the car in my possession, good luck!!

@canobd2 I have a 1968 pontiac catalina with a 400ci v8 engine and I was told by my mechanic that i need to have the exhaust manifold replaced. I am very inexperienced with working on cars and was wondering about how much it would cost for a new manifold and if it would be best to get it professionally installed to do it myself?

[canobd2]

I would recommend you have it professionally done by someone you trust.  Good Luck!

You might want to also look at your valve cover gaskets, if they are leaking onto the exhaust manifold this can also cause a fire.

I just did this on my 1997 Mitsubishi Eclipse non turbo. If you want to see a non professional do it, check my page out. I'll have the video up very soon. I also added a cat back exhaust on my video and will be adding another vid where i de cat my car.

This is great! I got a crack in mine, and it's a 1999 Honda Civic LX, I hope they're pretty much the same as this 2000 model, because I just got the replacement manifold/converter in the mail yesterday and will be attempting this repair within the next couple days. Thanks for posting this!

@pienapple13 Hell man get headers and put a carb with a higher cfm on it. You going to replace a manifold might as well get a set of stainless headers. Get more power better fuel economy better sound and you won't have to worry bout a manifold cracking again.

Yes, I would recommend replacing you leaking exhaust manifold, this could lead to other problems if you do not replace you cracked manifold.
