Getting True Dual Exuast
I have a 1997 F-150 with a 4.6L
I am wondering how I am able to get true dual exuast. Meaning I want to have an x/h pipe (like the ones mustangs have) that leads into two seperate mufflers.
I do not want one muffler with dual outlets. I want to be running 2 (completley seperate) mufflers.
I have searched on-line many times and have not found a company that makes such a thing. Do I have to have this custom made? or is there a company that makes this.
I want this to be without cats also!

You can get it done, but it has to be custom. Look at my photo gallery, I have a true dual Magnaflow setup with an X-Pipe, but I also have hiflow cats. Check mine out, and ask any questions.

It would be cut the factory Y pipe, install a new 90* pipe on the drivers side to line up with the pass side.
This is where the X pipe gets installed.
Then the output of the X pipe is connected to 2 SI/SO mufflers.
In the picture above, you can see where the new pipe has been added to the factory pipe, to create the turn on the driver's side of the xhst.
If you are removng Cats, you can only remove the second set and put in the Casper O2 simulators, or anotehr similar item.
1st set of O2 sensors and cats are needed by the PCM to run the truck, cannot get away from the PCM checking A/F ratio and the emissions section of code.
The gain of not having the second set of cats is not that great to not leave them alone. If you are really squeezing out HP, then high flow cats and headers are in order, but this is a chip reburn item, and after items like electric fans, and pulleys, maybe even MAFS & injector ( rail & pump also ) upgrades which are also reburn items.
All in all, just take into account how much you want to spend on the system, and then look to what you can get with that dollar amount. Remember true dual systems are to use 16 ga 304 stainless steel pipe ( $$), not aluminized steel pipe.
Aluminized steel pipe allows the xhst gas to cool too much and loose the scavenger effects of the hot gas flow through the system, in other words defeting the purpose of the true duals to start with.
Depending on the shop and the mfgr of the parts, true duals run about $900.00 and up when done correctly.
Let me know if this answered the question I thought I read ( aka did I misunderstand the question at hand ).

That is basically what the 2nd lightnings are doing. If they go with an aftermarket company like bassani. I figured this would have to be a custom job
The thing I wanted with my truck though, was a way to figure out how to get the exuast to exit on both sides of the truck. I basically want this, stock headers (upgrade later) going almost directly into an x pipe (or crossover like you have) then directly into the mufflers. You know how the exuast looks on a 2nd gen lightning right? I want that same look, but on both sides of my truck. I wish to have 1 muffler with 2 tail pipes go out the left, and the other muffler with 2 tail pipes go out the other side. Now I just have to figure out how to that. I might do the same as you, but rather have 1 of those mufflers tail pipes go back towards the front of the truck, up past the fuel tank, then back to the back of the truck, on the other side of the fuel tank. And finally out the side at an angle.
If you have ever seen a 2000 Cobra R, that will help you get a general idea as to what I want my F-150 to have!
Nice pictures also, and thnx for the help.

All though I hardley know anything about aftermarket products for F-Series trucks, I know a whole crap load about winsor and modular engine (mainly in mustangs) and also LS1 engines. For modular engines in stangs, to run with out cats, all you need are MIL eleminators, will this work with the F-150 also? Or does the mustang computer diff from that of the F-150, dealing with cats and the 02 sensor readings?

Josh,
If you know how to eliminate both sets of cats on a Ford, then you know a whole bunch more then me, so ignore my pontifications about the 1st set of O2 sensors.
I have not seen a set of MIL elminiators used in the first O2 sensor positions, as if you simulate this, I would know know how the PCM gets the A/F ratio voltage level to adjust Injector pulse width. I have seen quite a few in the second O2 sensor positions.
If you got that one down pat, you would be all set in taking out both sets of Cats.
As far as trying to do a forward dump on both sides, I don't know if you can cut the bend from the drivers side to the X pipe and then back to the drivers side that quick. I guess you would need to ask a tuner that question. Also this would have the xhst pipe running right under the gas tank on the F-150, and either trying to go over or under the drive shaft. A lot of bends in the system, that might cause the flow to get severly jacked up. All guess work on my part, you would need to ask a tuner about this type of setup.
If you wanted to do this I guess you could do with SI/DO mufflers on each side of the X pipe, but I don't know how well this would work with the 4.6 or 5.4, never seen that one done.
Good luck with the install

Yea....sorry about getting rid of all 4 cats. I didnt ever look at the exusat to see how many cats there were. Just figured it was like the 99+ GT's and only had 2. I guess you do have to keep the first set of cats, or program ur computer to get a reading some other way.
This is what I am thinking as of now. Since getting exuast done after the headers, and before the muffler is a pain in the ***. I think i am just going to do this. Install a 40 series flowmaster muffler, SI/DO right after the 2 sides of the exuast come together. So that muffler will be right after the 2 pipes come together. Then on the DO side (where the pipes go) I will get (2) more short Y pipes. To make the dual outlet become a 4 pipe outlet. So 1 pipe goes into muffler, then there are 2 pipes coming out of muffler, and right away, those 2 pipes split up and become 4 pipes. Run 2 of the pipes along the passenger side, and exit like a Lightning does. Then run the other 2 pipes under the driveshaft, and everything else.
Note: My truck has 33's, and I dont go off roading, so I am not worried about my exuast pipe being 2 inches (or whatever) below the rest of the car.
Then once it gets close enough to the driver side, past the gas tank. Run it towards the back of the truck, and exit out the side.
So one of the exits from the muffler, will go straight back and exit on the passenger side.
The other exiting pipe (that becomes 2) will bend right and go across the truck (maybe less then a 90 degree angle to help the exuast flow well) then go towards the back off the truck, and exit out the side.
Then I have "Lightning" looking exuast on both sides.
I am not to worried about performance, the main reason I would do this, is because I like the way it looks.

If looks are what you are going for, then routing pipe 'under' the driveshaft is not going to look that good IMO.
There really is no economical or aesthetic way to get pipes out the drivers side in front of the tires.
The reason you can do it on a 'stang is that the pipes from the headers are symetrical in their route to the mufflers. These trucks just can't route that way.
Remember, your truck weighs a lot more then a 'stang, and it needs all the low end torque it has just to get out of it's own way.
Duals are fine, but you have to build them in a way that won't take away that much needed torque.
JMO on this. I too had a 'stang and wanted to have the same exhaust setup, but found out that comparing the two is like comparing "apples and oranges"......
Good Luck!

Yes I know the F-150 is different from any mustang. My 5.0 had long tubes, off road x pipe, and borla exuast. All put on by me, in my driveway. With simple tools that everyone has.
I don't think people will be able to see the pipe going under the driveshaft, and if they do....they wont know what the f*ck it is. They will just see the 2 tips of the exuast exiting right in front of the tire. If someone where to ask, what that piping is under there (assuming the person is just some Joe Schmoe) I can just say, its for the turbo exuast manifold. And they will believe me, LOL.
If I ever get this actually working, I will post pics for you guys. I will even try this weekend to post pics of what I *hope* the exuast would turn out looking like if I did do this.
I am not going for a mustang setup here...just one that has tips on both sides.

No thanks, I do not want my tips out the rear...everyone has exuast out the rear!!!
Only truck you see consistantly out the side is the Lightning.
I do want my exuast like the lightning, but on both sudes of the truck.

The302Riddler,
Loose the fuel tank in favour of a fuel cell mounted where the spare goes and you will have all the room in the world. It is not an easy solution to what you want, but the only way to get the pipes in place is to move the tank.
