so he dumped the efi, to go carb.

 

Nothing like going backwards 30 years in technology, efficiency, and reliability.

But then, I always have to laugh when I read how folks believe that a "smog pump delete" is somehow a "good" thing.

 

 

What about a set of Wheelwell headers? with some magnaflows dumping out in front of the rear tires? Thats what I did. cept I went with the Moroso stainless spiral mufflers. Quieter than the Purple hornies I had on it, but not by much.

 

I don't know much about exhaust, but I have a 1993 Ford Bronco with the 5.0. What I was thinking about was getting long tube headers, and I wanted to get dual exhaust, and route it out the sides in front of the rear wheels on both sides. My dad keeps telling me you can't get dual exhaust on a Bronco because of the fuel line goin up the drivers side of the truck, is that even remotely true?

 

When I had dual 3" on mine (about 2 exhaust systems ago) the shop wrapped the tube around the frame straight off the header and ran it down the outside of the frame and dumped them in front of each rear tire.

Unfortunately I had some issues getting the O2s hooked up so that system lasted about 3 months.

 

Fuel and vapor return lines do run up the inside of the driver's side frame rail. The fuel filter is also mounted to the inside of the frame rail immediately below the mid-section of the truck. Too much heat in this area (other than the obvious dangers) can cause fuel delivery issues.

With the EEC-IV system, you MUST have a cross-over ("H" or "X" pipe) in the system so that the O2 sensor reads the exhaust from BOTH banks of cylinders. If the system only has an O2 sensor in one pipe, the readings taken by the O2 sensor have the potential to be extremely inaccurate (reading the exhaust output of only HALF of the engine) causing significant performance and fuel economy problems.

The "geography" for running duals on either side of the truck gets contrived to say the least. (t-case, fuel lines, transmission crossmember, that gigantic fuel cell, etc.) The OEM exhaust routing is the clearest and the most successful "dual exhaust" setup I've ever seen. The system ran both pipes down the OEM path with the cross-over being almost exactly the same place where the OEM Y-pipe arms met. (This also made it possible to use an un-modified O2 sensor wiring pigtail).

 

it would be much easier and cheaper to run single exhaust and a single in/dual out muffler then have the shop route the pipes like you want. Frankly there is no performance improvment with running duals on our broncos due to all the bends in the pipe to run it correctly like Greystreak mentions above. purpose of duals is to run the pipes as strait as possible.

I have only seen 1 set of fender exit headers for our broncos, with that said i have no idea how well they would work and if the tires up front would end up making contact or the radius arms hitting them as well.

also understand that long tube headers never go in easy and if you ever plan on installing a solid front axle at any point the long tube header on the passenger side will hit the front driveshaft.
