I have a 2005 F350 stock exhaust. I have another complete turbo back exhaust at my house for some reason, not sure why. I was looking at the MBRP 4 inch turbo back with out cat and muffler (straight pipe). My question is what is the difference between that and me taking out the stock cat and muffler out of my spare exhaust and welding in pipe to make it, in essence, a straight pipe?
as for mods It has a filter, and an Edge juice with attitude platinum. I drive it daily to work and from work and I tow 3-4 times a year so I am not hard my truck in any way. I know the edge isnt the best but I believe for what I am using it for its ok? I am sure 95% of the people on this site use their truck for what it was built for, sadly I am not one of those people... yet
