Down Pipe and Wheels

[AFLOADTOAD]

Im new here and to powerstrokes but when I was looking under my truck I saw this crazy flat downpipe and thought thats gotta go. So, my question is will a 4" fit without major pounding? Or should I go with a 3" or 3 and a half"?

Next question concerning wheels. Can I directly fit newer ford wheels to my 97?

Well what do you think?

4" down pipe won't fit without extensive firewall modification. 3" down pipe is what most run.
Super Duty wheels will not fit. Wheels from a Dodge or Chevy 8 lug will.

Thats what I though about the downpipe. As for the wheels I can run say 3rd gen 8 lug dodge wheels?

Yeah any Dodge 8 lug wheel will fit. The only thing that won't is a 99+ SD wheel. Why Ford went to a metric bolt pattern I'll never understand.

Dodge steel wheels won't fit. I found out the hard way.

Must have been from a 2wd with the small hub opening?

No, they fit on the hub but hit the calipers. I could've possibly fixed em by grinding down the calipers or inside of the rims but i didn't wanna risk messing anything up so i just used the stock Ford steels.

When you say steel wheels do you mean the ones that come off a 1999 slt 16's

No, it wasn't them.

I don't know what they came off of. I was only told that they were Dodge 8 lug rims, and they looked like the OBS and older Ford steel rims.

You don't need larger than a 3" DP unless your making over 500HP..

Can you run SD wheels on a OBS yes..we can get you everything needed to swap SD 99-10 axles under your truck..
