My first modification will definately be exhaust . I would Like to go with longtube headers and either dual or single 3" exhaust . What do you guys recommend? I am a Mustang enthusiast and know the aftermarket for them inside and out but I am not sure about the Bronco's and my 351 . Does anyone make a kit? What design is best for performance . Emissions is not an issue .

Any reason for wanting to run longtubes? As for running duals, I wouldnt. If you ever plan on running with the rear window open, or the top off, its just going to create a vacuum and the exhaust will be pulled into the cab. Most of the 3" single catbacks work as well, or better than true duals. Also, I have yet to see anyone who makes duals for the bronco. Wait... I believe Dynomax makes them for 80-88, but thats it. Is there no emissions testing in your area, or are you just not going to use your emissions stuff?
Gibson makes a nice set of shorty headers, which I have on my Bronco. I am running a sigle 3 in tube with a 2 chamber flowmaster out of the stock location. The headers make a huge difference in throttle responce, and the sound is nice. I wouldn't recommend dual out the rear either. You get enough exhaust thru the rear window with the exhaust in the stock location.
I've got a complete stainless Bassani system. Ceramic shorty's, y-pipe, high flow cat, muffler, and 3" exhaust. Ran about $825. Even came with stainless clamps and a very nice 3.5" chrome tip. The tech at Bassani claimed the single made more power than the dual system. He sold both so I didn't have any reason to doubt. You might look into this system. Workmanship is excellent and fit like a glove.
Go with gibson shorty headers. They are a really nice piece. Only heard good things about em. Avoid Summit headers, as they are reselling what ever they have in stock. Sometimes they work, sometimes they blow big time. I tried mustang shorties, but the exit on them just wasn't gonna work out. I've also heard that if you try hard the gibsons will bolt right onto the factory Y pipe. And go with true duals. I just had it done, and its worth it. Big time throttle improvment. I went with stock 2 1/4 pipe, as i'm running a 302 with no real modification, and it's only a 302.
The problem with true duals is on the drivers side they hang low because of the t-case. This can cause issues if you are wheeling. with the pipe being exposed like that could get torn off or bent up then youll have to take it back to the shop for more work. I went with the summit shorties because of money issues but got lucky because they were flowtechs. They bolted up great, and just needed the collectors on the stock Y pipe enlarged and had a new flowmaster and 3" out the back. Really its the way to go. looks cleaner, and is tucked up out of the way. wont have to worry about it getting messed up on the trail. Not sure about running long tube headers, i do know that if you run them with duals the headers can crack when the fram twist during 4x4 outings ive seen it many times.
Why do true duals have to exit out the back? On my '88 F-150, I ran full length headers and true duals with no problems. The driver's side went under the tranny where the y-pipe goes, and both exited out the side behind the rear passenger wheel. This way, you don't get exhaust inside with the back window down, and you don't have exhaust pipe hanging down to get banged up.
Problem with that is its not a true dual setup. true duals go strait down the under side with drive train in the middle then either exit out the rear or just behind the tires.
Having "true duals" has nothing to do with where the exhaust exits from under the vehicle. All it means is the exhaust from the left and right banks of the engine stay seperate all the way from the engine to the tailpipe. Doesn't matter if they are on the same side of the vehicle or not. As long as they never mix with an H pipe they are "true duals".
well i was under the impression that the purpose of duals was to get the exhaust the least resistance which would be strait out the back with as little amount of bends possible. The setup he was talking about seems to me much the same as going with just a single 3" because of all the bends and turns. I know the lightning exhaust is similiar to what hes got but theres is also alot straiter to.
