Does having a turbo back make a significant difference rather than a cat-back because i want a 5" exhaust and its like 200 dollars cheaper for cat back.

Yes get the turbo back. Makes a nice differance in the EGT's. My truck dropped about 250degrees in the EGT's when I deleated the Cat. And the truck sounds great.

Should i save the money and get turbo back 4" or go all the way and get the turbo back 5"?

Theres lots of info on here, you should search. but theres no need for 5" unless your putting out tons of power

unless you are going to change the turbo, or go with twins a 4" is more then enough.

4" is all you need, but 5" has great sound and looks if you are into that sort of thing. Yes, there is a big difference from cat-back to a full system. A cat-back system will sound very close to stock, a full system will have a low rumble and loud turbo whistle.

x2 ^nate^ is who i got my 4 inch turbo back from and i'm very happy w/ it. if your goin to delete the dpf, you mite as well get rid of the "cat" to. don't know about your state regulations, but from what i see in most of these threads, you don't even need the cat for inspections. just a muffler. good luck.

Nate, jsut got the Magnaflow on today.....

cant beat 335 shipped with the tip..... Stainless to boot.. I almost went with the Jardine, But when I added the tip and shipping it was around the magnaflow price....

I was Out there putting the exhaust on and it took about 2 hrs 45 min and I had dinner and was talking to the neighbor within that time..

take it for a drive tommorrow, see how it is....
