how much power is really needed to flow the air that requires a 5" pipe. Im just trying to see if its over kill for what im trying to do.

You probly dont need a 5 inch if your just getting a chip and other minor mods, fill out your signature and you could get some better advice.

I agree, 4' will do just fine.

I had a 5" on my 2000 f350 and loved the sound. Looked badass with the 6" tip! I still have'nt made up my mind on my new truck. May go with 4" because they are cheaper.

A 4" will flow more air than you will ever need and then some but the 5" just sounds awsome.:happydance:

i Have seen your vid on the elite site. those are some good runs. what size are you using with all that power.

The mbrp 4" off road is the one that i want because it has the cat delete pipe. I found out that it has only a 3.5" downpipe. Why is that? Is that how most 4" systems are? you think it would a 4" down pipe. If anybody has info on this please let me know im bambozled haha. thanks.

Not all systems have that.I have a Bully dog 4" dual from turbo back and sounded real good. It was pricey though. But the down pipe is 4".

I've a 2003 f-350 dually with a 7.3 and I purchased one of those new edge evoloutions with the three stages. I don't how hard it is to install. I know little bit about them but I'm more mechanical guy then electronics. I also want to put a turbo back exhaust. But i need the fuelmilage and power.

OK, we are talking about two different exhaust. On a 7.3 superduty 99.5+, you can get a 4" DP in there very easy. It is not so easy on a 6.0L. Most all of the exhaust for the 6.0 are a 3.5" DP that do into a 4" or 5" out the back. There is just not the room with a 6.0 that there is with a 7.3. I don't know why, and it does not really make sense. That is just the way it is with the two different setups.
