Hey Guys,

Been looking at doing a turbo back exhause, deleting the cat. 4" or 5"? Also, anyone have any experience with Diamond Eye Performance? Here's one for sale on Ebay

I don't want it to sound obnoxious tho...

i have only been a PSD owner for about 2.5 years and never did anything to my first truck (06 model) but i just got 4" turbo back system put on my 04 truck yesterday. it does sound different but i'm not sure there was a huge power difference. we'll see how the MPG does next tank fill up.

the biggest change came when i unplugged my freakin' crappy EGR valve thay must has been stuck wide open. that was huge.

i dont regret spending the money since it should help EGT's when pulling the toy hauler. a cool engine is a happy engine, they say....

Go with 4 inch turbo back and get rid of the cat.
Also want to do is do a EGR delete..get rid of the valve and cooler..your truck will run much better and the turbo will run way cooler.

I've done both and the truck has never run better.
