Straight Pipe?
Besides being way louder what are the actual benefits to getting rid of the cat and muffler in a diesel?
Is there that big of a difference between 4" and 5"?
I'm trying to push more power out of my truck and I think starting with the intake and the exhaust is a good start.

The biggest gain would be gutting/removing the cat. Followed by a 3" (or 4" if you're brave) down pipe. A good air filter (not K&N) is also beneficial. You should look into the 6637 mod or the filter in my signature. (I think I'm the only one here that uses it.)

Been looking around for turboback kits. (Don't want to run a 4 or 5" straightpipe from a 3" down pipe on the turbo. Figure that defeats the purpose.)
Anyways I found this diamond eye 5" turboback kit. Anyone ever run one?
I'm strictly looking for power and performance from this. Granted I love the sound of the turbo whistling but I don't want it to be flat out obnoxious.

Looking into that 6637 mod as soon as I get home.

A 3" downpipe into a 4" or 5" exhaust will not "defeat the purpose." That is just a common misconception. A 3" downpipe is probably good to 450 - 500 HP. Plus anything larger than a 3" is a major PITA! A 3" is hard enough. If you read the description for the kit you posted in that link, it says it comes with a 3" downpipe.

I have the 4" system and love it, but I've never heard a 5" system as far as I know.
