[gcfd856]

I am going to put a new exhaust on my 2001 7.3. looking at magnaflow should i get 5 in. or will 4 in. be ok .and should I put muffler on.

On a 5" you lose bottom end. IMHO.

4" straight pipe. heck i have stock straight pipe and its fine.. but if you want to then go for it.

I like my 5", and didnt feel like I lost any bottom end

4" is just fine, you arent going to gain anything going to 5" unless you are talking a serious mods. Just get a big tip and save come $ on buying a big exhaust.
