ok so i'm thinking of putting a set of headers on my 93...i've got an off road pipe on it w/ flows but they are mounted to the factory mans(i bought the car this way)....is there a set of headers i can buy that will be a direct replacement so i don't have to cut up my H pipe? If so what are the best for my $$?

Most any of the shorty headers should work fine.

thanks!!! do you think any are better then any of the others? i had ceramic coated long tubes on my 69 mach 1 and the finsih didn't hold up, but they looked great new....i'd like to add a little pop to the engine bay but don't want to have to clean them all the time....

I run the BBK 1515's, which are just the chrome ones, yes they don't stay chrome forever. But not any problems with them at all though.

Me too. I'm switching over to the ford racing ceramic coated shorty headers, until I have the $$$ to get the gt40p heads installed. They work with normal and P heads. :thumbsup1:

shorty headers are really a waste of time....exhaust tone will change a bit..

longtubes are the way to go

I wouldn't say they're a waste. A hell of a lot better then the stock manifolds.:yes1: I would have went with LT's, but the only company that make them for the AOD is MAC, and IMO, MAC is garbage, not going on my car.

I have a 89 Hatch and I went with BBK Chrome Equal Length Shorties. People say that they are no difference with the equal length versus the unequal length. But in my opion the equal length gave me more touque than the unequal. I talked to the guy that came up with the Superchicken for for in the late 90's for Sema. He said long tubes were a waste of power for the 5.0's unless your running big CI's. He came up with the supercharger for Paxton so he should know his stuff. Hope this helps you out some.

i agree that unequals may add some over regular shorties...long tubes actually can fatten up the powerband and give more tq and HP..dyno proven...now this is only true if your tune is adjusted accordingly..big CI's and 5.0 shouldnt even be in the same sentence...lol

tune tune tune....even a bone stock EFI 5.0 can make power with a custom tune.

There was a mag test a while back -- mild 347 (around 340 rwhp) that they tested - 1 5/8" equal length shorties, 1 5/8" non-equal shorties, 1 5/8" long tubes and 1 3/4" long tubes. At peak HP/torque they were all within 2-3HP of each other - within the range of repeatability on the chassis dyno = no difference at all. However, the long tubes produced significantly more low end torque - as much as 40 ft-lbs. more for the 1 5/8" long tubes, 20 ft-lbs. more for the 1 3/4" long tubes (too big to be optimal for this motor).
