Alright, I've done it one with a cheap apn stainless manifold last summer and that one has already cracked again. What manifold/header will last without cracking and/or has a lifetime warranty? Thanks. I'll keep searching myself but figured someone might have the answer to this beaten horse.

 

How are your engine and trans mounts?

Use a flex pipe.

 

Id like to tag along on this thread (not a hijack!) I'm in the market for one as well. I was set to look at APN, Dorman and possibly the eBay discount items if people can give them two thumbs up. Fitment is a big concern as I've read various accounts of tabs being too large either by width or in thickness. Also, many sellers list the same manifolds as fitting the grand and wranglers. Not sure if that means you can MAKE them fit with a hammer's persuasion. I don't really want to bash on my new exhaust to make it fit.

 

All that may be required is a little intake manifold filing.

 

brand new brown dog motor mounts rubber and brand new trans mount rubber.

 

Oh, so they are new. What were the mounts like during MOST of the header's life til now?

Did we shut the barn door after the horse got out?

 

I replaced the mounts a few months after the new exhaust manifold, they were never in very bad shape I just figured they're 17 years old so might as well replace them.

 

Okay. Flex joint.

 

don't those leak?

 

If they break, yeah.

 

How do you know a crappy APN header isn't going to just crack itself anyway under the stress of heating and cooling? This isn't the first time someone has posted this complaint about those headers. They just don't seem to be made that well.

I love my Banks header, but it has less than 10K miles on it, so I can't speak to how long it will last. They have a 5 year warranty IF you buy it from an authorized reseller. I got mine $100 cheaper from a guy on Ebay who bought it new and never installed it. I figured it was worth the gamble.

I think Rugged Ridge also have a 5 year warranty. Borla has a "million mile" warranty on headers, but I don't think they make one that will fit a '99.

 

I like my stock manifold. it's only 19 years old with a few hundred thousand on it so I have limited input but works good.

 

So then, anyone care to share their experiences with either Dorman or the eBay mystery manifold? I'm not spending the big bucks buying borla or OEM for my limited use rig.

 

I just installed a Dorman and flex tube about half a year ago and have had no problems yet. Everything bolted together as should with no fitment issues. I'll post a link to my YouTube video in just a sec

Edit: here you go.

 

Because I've used them for over 5 years with no issues......Cheapos from ebay.
