Headers are leaking!

There are gobs of low end torque to be scavenged by quality LONG TUBE headers. Don't waste time or money on shorties. I'd recommend a new Y-pipe setup from a reputable exhaust shop. Shouldn't cost much for them to bend and weld a Y for your friend.
Whether you go with an OEM manifold or an aftermarket header, I'd highly recommend high performance copper gasket sets. Once they seal properly, you will never have gasket failing problems down the road.
Good Luck,
Mike

Sorry, i forgot to say that it is a 2003 Ford f250 5.4L with about 80,000. It has a dual exhaust on it right now, and than he started hearing loud noises coming from the enigne, they tested for leaks and found the header was leaking. he wanted to know if he should go with aftermarket or stick to the oem from ford, and if aftermarket, what makes are good
thanks for all the help

Does that mean the stock y pipe is removed? Or do you really mean he has a cat back muffler with one inlet and two exits?
Regardless, his OEM manifolds will require removal and installation. If it were my truck, I'd upgrade to a set of Gibson (or other reputable brand) aftermarket manifolds.
Regardless of which way you go, replace the gaskets with a high quality COPPER gasket. They take a while to seal, but NEVER leak if properly seated.
Hope this helps....

It probably has a couple of broken studs in the head. I would replace these and save the money on the headers.

Somebody is probably gonna get mad at this idea, but an old racer that I bought some long tube headers from, told me to not even use gaskets, but instead put some hi-temp silicone on the headers, let it cure for an hour, then bolt them straight on, and according to him, it will seal better than gaskets, and it doesn't get so pricey when you have to replace them every year.
I tried it on my 302 headers, and so far it doesn't leak a bit.

I've got headers on my Tbird, and it doesn't leak with the OEM gaskets,and these gaskets have been reused a few times too over the last 5-7 years.

Spend the money on a good quality copper gasket (I prefer the flanged Mr. Gasket variety), have the flanges machined straight and the headers will never leak. They take a long time to seat, unlike the other gaskets, but once seated they are bulletproof.
Oh yes, I drive the hell out of both of those trucks.
Do it right the first time, and you won't have to replace gaskets.

It runs 12-teens at 110+mph in the 1/4 mile and weighs 3600+ lbs. N/A and with an automatic....You seem to know so much-you do the math as to whether it gets driven hard or not.Proper installation is key to keeping a modular header sealed.It's just like this horrible "defect" of the cylinder heads on modulars puking plugs....it all falls down to the guy at the end of the wrench. Crappy installation=crappy results later.
