Anyone Dualed Out An Excursion?

I have a 2001 Excursion with the 7.3 powerstroke. I'm thinking about dualing it out. Anyone have any recommendations? Any sources for materials?

Any comments about this will be welcomed!

I thought it might finally be worthwhile to put dual exhausts on the beast because of the high diesel prices as it should increase my mileage by 1-2 mpg.

Is the factory single exhaust system stainless?

Thanks

Hmmm, I didnt know putting duals on could increase your fuel economy like that. I just thought it looked cool. If thats true, thats awesome! I believe your factory exhaust is aluminized. Are you looking into the MBRP "Cool Duals"?

Welcome aboard!

dualing

I know that it will give better mileage and some additional hp. The thing does have a 60hp chip. The chip makes it run like a large block gas engine.

I had read somewhere else about the increased mpg. I guess that the only way to find out for sure is to do it yourself.

I tok this thing on a raod trip from GA to TX. I left Ga w/the tank topped off. I stopped in longview TX to fill up & still had fuel left in the tank. I set the cruise on 70-72 mph. I got 21.5 mpg on the interstate trip stopping only at 3-4 rest stops. It was embarressing 'cause the 18 wheelers were passing me.

Stock exhaust is not aluminized or stainless, it mearly has a thin coating to help prevent the corosives in diesel exhaust from eating throug rapidly.

I'm all for getting better milage, but at what cost? if you are only doing it to get better milage and increase the performance then it would not be a cost effective decision IMHO. if the kit cost 800 bucks then how many miles and how many gallons of fuel will you ahve to burn for it to pay for it's self?

Cool Conversion

I know how to put the duals on but I'm not shure of the reason to do so. I can't remember the name of the outfit that sells the wheel adaptors. They are 4" thick cast steel. If you look in the back of most truck mag"s you will see them or search with google. With my F-350 i got great stablity when towing at the cost of some fuel milage. I used stainless wheel covers so I could rotate tires. They were a real pain in the snow. If it was a little deep and the road was traveled by single tires ahead of you, The outside duals don't have a path to run in. They are cutting a new trail. To put out in plain english, your all over the road.

Good advice Kiarasue, you thought the same thing i though of at first. However this thread is regarding dual exhaust. Not dualie rear tires.

Although being from Oregon and currently stationed in SC i have seen both E-series and Excursions with dualies.

Cool dual's

Man -o-man, I got all worked up for noth'n. When I got my X I talked about the dual wheel thing and two of the my three kids and my wife jumped to say NO!!! I have seen some F series trucks with dual exhaust. I have an Excursion and things are kind of crowded in the back. The systems I have looked at have a single in and dual out which seams restrictive and a pain to get around the spare and shocks. I was just outside looking at my X and superduty. I have a 4" on the X and am going to put a 5" on the superduty. On the X I had to move the right rear shock over 2" so it didn't rub. I put the muffler that looks like a glasspack on backwards to lessen restriction. Loud or quiet, Diesels don't like much back pressure. I have owned some big Cat and Cummins engines and they all responded well to free flow mufflers. Pyro temps are lower and fuel mileage increased. I guess what I'm saying is go for the performance over the style.
