Dual Exhaust

Car is '88 Sport 5.0 w/AOD. I want to fabricate a new 2" dual exhaust from the iron manifolds back to the existing Flowmasters. The transmission shift link and shifter cable are right smack dam in the middle of where the the LH pipe needs to go under the double hump crossmember. Before I make a crooked pipe to fit, what sort of brackets and shift lever do cars with factory duals & AOD use? I would like to see photos of MkVII, Mustang, Cougars, any Fox 5.0. or any advice on what brackets I need to look for in the junk yard.

I also have a Sport. Here's what I did......

BBK unequal length shorty headers
Pype's Off Road X-Pipe (I barely flattened the inner side....about 3 inches long and 1/4 inch deep......to clear the shifter linkage
-And worked the rest out using bent pipe from the ler shop for mid pipes,muflers,and Mustang tail pipes. Easy and it flows great.

Yank the AOD, install a T-5, and swap out to a TC steering column.  No more shifter linkage issue...the expensive way.  All kidding aside there are a couple of threads on here about this very issue of which the search function can help you find.  Also, nix the 2" pipe and run a minimum of 2.5" as the 5.0 will respond better to it.  You can scour the Mustang sites and pick up a set of used shorties for cheap but make sure the header  is one piece (where all the tubes weld in at the head) and at least 3/8".  This will keep it from warping and causing all kinds of gasket leaks.

Here is one of the threads that goes into some good detail:

Not long ago, I noticed how far the shifter linkage sticks out into the area where my h-pipe is going to run past my floor-shifted AOD.  You'd think Ford could have done better than that.  This HAS to be a problem on Stangs and Mark VII's.  They come from the factory with duals & AOD's.  Oh well.

By the way Darren.  I LOVE your avatar!  I guess it's true that everything's BIGGER in Texas!!!

All of the 85-93 Mustangs were center console shifted thus cable shifted which means no shifter linkage to get in the way.  Not sure about the Mark VII's so maybe someone can chime in there.  I would think that since the Mustangs and Mark VII's were factory duals on the 5.0 cars Ford would have designed them to accomidate the dual exhaust.  As usual there is just a little more hot rodding involved when it comes to our cars.

I believe the pic in the avatar was taken in Norman, OK at a football game as the surroundings look like one of the exits by the south endzone.  I was born and raised in the Sooner state so being an OU fan south of the Red River is especially fun.

I believe there are H-Pipes for auto equipped Stangs (which fit our cars if we have headers). As I stated,a mild flattened area (not crushed) for about two inches can fix the clearance problem with no effect on performance.

I used to do all of my grocery shopping in Lawton at the base because the Army Commissary was better than the A.F. store where I was stationed in Altus. Lawton was where we did all of our shopping.

Oh man, Altus...I lived there for three years (2000-2003) when I was a controls engineer at American Gypsum (wall board plant) in Duke, OK.  Yeah, let the good times roll in Altus.

Sorry for getting way off topic here.

If those Mustangs were center console shifted, has anyone here installed the shifter linkage from a Stang onto their Bird?  It's the same chassis and same tranny, so it should be an easy swap.

Thanks for all the posts, even the ones on topic. I'm a transplanted Okie too (Enid). Sorry this took so long but here are some pics of the situation under my car. I meant to go to the shop and take these pictures Monday, but that was three Mondays ago now. We had a blizzard and the road here still looks like a luge course. Wouldn't be driving the bird in this ice and snow even if it were at home. So these pics show the bracket for the cable being the primary offender. It was apparently designed with no consideration for the double hump crossmember already in place. And the cable would run a more relaxed and natural route if it were raised, too. It looks like the end of the bracket can be chopped off and the existing metal will provide the material for a relocated cable end. If I measure it correctly the lever will still work as is, or the lever could be bent a bit to enhance the extra clearance. But I ain't cutting up my bracket until I have in hand either another one or a different one that fits better. There has got to be one for a Mk or maybe XR7 but I can't find any pictures of one so am headed for the junk yards as soon as the snow melts...June?

I looked over on the Corral for about an hour and there is all kinds of conflicting information but everyone there says this guy is the man when it comes to AOD's.

Go to his site and give him a call and I bet he can figure it out.

Looks like a T-5 is gonna have to be installed to ease the installation of the Exhaust.
