Aftermarket Exhaust Manifold for 7.3L Turbo?
Hey Folks – Nice site.
I have a 1996 F250 7.3L Turbo Powerstroke in need of new exhaust manifolds. OEM from Ford they’re $350-$400 each. Dorman sells them through distributors for about $160. I’m assuming these are some Chinese imports – but has anyone had a bad experience using Dorman (or other aftermarket manifolds) on the 7.3L? I was ready to go OEM but for the price difference I have to give aftermarket a look.
Thanks!

The local dealer said they’re warped & I can hear the exhaust leak on both sides of the engine compartment. They said they usually only see it on trucks from snow country – which is where this one spent most of it’s life. I also know the original owner & have know the truck since it was new. The guy loved to keep the engine compartment clean – by taking it to the car wash, opening the hood & blasting away. Probably not a good thing to do.
I’m going to take it to another shop for a second opinion since this is not something I’m looking forward to doing myself.
I’m leery of bone-yard parts on an application like this. I’d rather go new if the aftermarket manifolds are OK, especially since I’m going to install a new 4” exhaust system as well.

I checked this morning & no bolts are missing. And the more I thought about it, how the hell could the dealer tell if the manifolds are warped without removing them & they’ve never been removed. Had he said they were “cracked” I might go for it. Now I’m wondering if they were just trying to give me a wall-job. A $2,300 wall-job. Guess I’ll crawl around in there myself before I go to another shop.
Yeah, just wanted to fix what is broke before I fixed what aint broke.

It’s under the hood. If I stand in front with hood open & rev it up I hear the leak. Sounds about the same on both sides but hard to tell. Don’t really hear it at idle. Under quick acceleration or under load it’s a thrap-thrap-thrap sound about in time with one or two cylinders firing.
I haven’t looked at my EBP but will take a reading tomorrow. Don’t think I’m losing much boost – it runs great but I’ve noticed a slight drop in mileage but that may be due to the excessive heat lately.
