Default Header fix thread...

Howdy-

So I have been riding a hole in my exhaust header for about a year now. It is time to get in there and fix it.

There is a small hole that has rusted/burned out. I bought a replacement header but it is a different size collector than the one currently on the truck... it comes in about 2" shorter than the "original" header and sits about 3/4" higher too.

So, would you:

1. Pull the existing header, cut out the bad tube, and weld in a new one.

2. Put on the "new" (used) header and deal with the redoing of the exhaust/building a portion of exhaust to fit and span the difference?

Neither are appealing, I am leaning towards option 1.

Thanks!

Drew

Have to agree....Pull it, start messing with it, notice several cracks and micro thin metal....then swap it with the other one after wasting a day trying to fix it. Have the used one cleaned and lay on some good ceramic rattle can paint the swap 'em out.

Yeah, I figured as much... but I was hoping for another option

Can a hole here at #6 cylinder be the reason that my brake booster feels weak? I think it is tied into a vac line there, correct?

Thanks guys, time to start the madness.

I've used this stuff before on raw metal. seemed to work OK if cured properly (in the oven..)

Has anybody had any experience with a better/different product? This stuff is cheap and available at autozone so i keep buying it for various projects.

VHT is great stuff! It's your call if you tell the wife what the horrible smell is in the kitchen! Still is accepted by the better than finding the T-case housing in the dish washer!

So I am going to buy a new header. I have two choices. MAF and JT-outifitters. JT's is the one peice flange variety and is about 75 bucks cheaper than the MAF who has started using a two peice flange, that they say, drastically cuts down on the leaks associated with header installation.

I can go either way, the $ now isn't that big of a deal to do it right. FWIW, the MAF product looks beefier and the flange is substantially thicker too.

What say you?

Thanks!

Drew

Maybe doesn't apply to your application, but for my header, I used ultra high temp gasket maker, and haven't had a leak issue with mine. It works really well. Just have to be careful not to put too much in so it doesn't spooge out and block the exhaust flow.

I just heard Downey went out of business. They made nice headers too.
