Hey everyone, new here.

[HFA_Ultima]

Hey guys I just picked up my 1997 Super Cab F250 7.3 yesterday. I really like to truck overall. I ran into a guy at our autozone with the same truck and talked to him for a bit and he told me to check out this site. This is pretty much going to be a pavement queen and a truck to tow my rzr around with. I have a 90 Toyota with 3" lift running 35s with lockers in the front and rear for my fun truck.

Im planning on lifting the truck and doing all the bolt ons. So far I made my intake, which helped more then I ever dreamed it would. I bought a edge evolution off ebay for 200 shipped, and have been reading not many people here like them after I got it. But for the price I cant complan much. Im looking at exhaust right now and want some input on that. I was thinking 4" would be good but my friend has 5" on his duramax and told me to run the same, so any opinions here? Its going to be turbo back of course, with no cat and no muffler.

Once my tax return gets here Im ordering a sky jacker 6" lift and some 38x13.50x18 tires, not sure which brand yet, with some XD Misfit rims. Hoping this will look pretty good, I like these older Ford trucks when theyre touched up.

I had read something about a j-mod to the idm but couldnt find that under search, can someone tell me more about this? And something about unplugging a valve in the exhaust that creates excessive back pressure when closed. I live in Wyoming so it gets cold here, and heard this is good to have when its cold. Is this something I can unplug during the summer and hook back up for the winter easily?

Well I think thats all I got for now, looking forward to some replies on everything stated. I like the forum so far, looks like a lot of good information and hoping I will fit in well here. Thanks!

- You came to the right place!

Sounds like you have a plan for it! Oh by the way, once it starts.....you're hooked!!! They will always something to do...

[HFA_Ultima]

Well thanks for the welcomes but any input on exhaust size and the mods questioned? Lol thanks

[SuperCrutyPS]

I went 4" Turbo-back. I don't know how much room the older body styles have to get a larger down pipe in. You might wanna check that out before you get one.

My truck didn't have a cat, but I did put the muffler that came with the exhaust. It is a flow-thru.

Just a suggestion.

I read that it wont clear with spare tire, but when I have 38s I dont think the factory spare will come in very helpful lol. With basic bolt ons is the 5" going to make any more performance? And without major modifications is it going to hurt performance?

[Fordman247365]

5" wont help or hurt performance over a 4", but it will sound a little better, up to you. If the exhaust pressure valve is working dont worry about it, but if it is acting up just unplug it, the plug is by the turbo inlet. Mine has been unplugged for 2 years and my climate is the same or colder than yours. For the IDM, well I would just find one that someone has modded or there are some diesel sites out there that will mod it for you.
Hope this helps

Well what is the mod? I work for Baker Hughes as a electronics technician so if is like modifying a circuit board or something I am more then capable. I just dont know what people are talking about and what gains there actually is.

As far as idm mod i have done many, very easy, Diesel Power magazine did a great write up on it several years back i have the issue just have to dig for it. As far as exhaust on all my OBS i just cut out the muffler weld in a pipe and then replace the downpipe from the turbo. On an automatic you have to loosen pass side motor mount and lift up engine but not much just enough for some wiggle room.Their are many places to buy the downpipe,usually runs $130.00 but then again everything keeps going up in price.

[Fordman247365]

The gains are worth doing and I am noth the one to ask how to do it lol, but yes it is simply removing one piece and putting a different piece in. It raises the voltage to the injectors, in short making them perform better
