Aftermarket Exhaust - Cat back or Turbo back?

I have had my '05 for about a week now and love it. I was talking to a local truck performace shop asking about exhaust systems. He said that on my truck that he would not put a turbo back system on because you increase your turbo lag due to the decreased back pressure from the removal of the cat. Any validity to this statement? My main motive for engine mods is fuel milage gain. I am considering an Edge Advantage programer & new exhaust. It already has been modified with an aftermarket K&N air cleaner system, but I still need to do the Zoodad mod - possibly this weekend. Thanks guys!

Your local performance shop is wrong. The turbo is variable vane, it will make all the back pressure it needs all on its own. Go turbo back!

4in FBD kit with a free flow muffler works out great.

Yes it does - mine is great! And the sound - well I've had several comments on how good it sounds - 'whooshing'. (Thanks, Gus)
And WELCOME to the Site!
PS. You might find out that your K&N may not be what you really want to have on your 6.0

Have you had a bad experience with this air cleaner? I didn't have a choice as that what was on the truck when I bought it. It sure makes the turbo sound great though!

I personally have a stock air box / filter. However I did install a power intake elbow, along with my exhaust. A very noticeable difference in sound, acceleration, and a little better mileage. I hear 'not too good' of the K&N's on this site. If you will start a thread about air intakes, be sure and mention what you have and what is recommended, and you will get responses from some very knowledgeable guys, maybe even some of the techs will speak up.
