CAT Back vs. Turbo Back
I'm going to order an MBRP 4" exhaust for my 06' f250 CC LB today, but I am having a hard time understanding what the differences would be between the two.
What would be the benefit of going with the Turbo back, and is there a sound/performance difference that would be gained by choosing to go this route vs. the CAT back?
I unbolted my muffler yesterday to hear the change in sound. I liked the deep "growl" that it produced, but it was lacking the "whistle" that I hear coming from trucks driving around my area.
In a nutshell, I need some opinions....
Thanks in advance.

If you want it to whistle, you gotta lose the cat and put on a good intake. That's what really makes her purr.
As for the difference between cat and turbo back. The trubo back has a larger down pipe that allows for more airflow. That will give you lower EGT's and better performance. It also allows you to lose the cat easily.
The cat back will still flow more air than stock, but won't whistle as well and allows the EGT's to get higher since the restriction is from the turbo to the cat.
NOW, about that warranty. They probably won't warranty most things on the engine if you go turbo back, but will possibly do it with only a cat back. Tough choice. I made my choice. I have an '06 with no warranty on it. I've done way more than the intake and exhaust. If the warranty is an issue, talk to your dealer. Just because they say they will warranty, doesn't mean everything though. You may end up at another dealership or a Ford factory person may decline it due to mods. Again, tough choice.

Exactly - my dealer said don't even think about putting on a turbo-back exhaust if I expect to have a warranty, however a cat-back is ok. So, I run a cat-back. Egt's are cooler, and the exhaust note is as silent as can be until you nail the throttle. I like it.

Thanks for the responses, guys!
I also spoke with my dealer today, and they advised to stay away from the Turbo-Back.
I pulled the trigger on the cat-back MBRP Pro Series.....should have it tomorrow morning.
I can't wait to put it on..

my techs said they wouldnt void warranty for exhaust or programmer if i was upfront with them and just them "wink"
next time you go to get an oil change go talk to your techs they are the ones doing the work to your truck, they are pretty cool guys most the time

Get the cat back and put in a cat delete pipe. That way you get the sound you want and if you have to take it in for warranty work it's only 2 bolts and a clamp to put the coverter back on.

Deleting the cat will only void the cat warranty nothing on the engine. I have a cousin that's a diesel mechanic for ford. But if you're still worried about warranty, get that cat delete pipe. You can't go wrong with that.

It didn't stop me from removing mine. Everything still runs great on mine as well. BUT, Ford is voiding warranties on 6L's with no cat. Besides, why would you need a warranty on the cat if it's not even on the truck?

6l pwr, so if i put a 4" catback system on my 2006ps with a good intake system like afe stage 2 magnum force intake system, i can get the loud whistle out of the exhaust and a little more performance from the engine? and the cat back should not void the warranty? will the cat back exhaust affect emissions test at inspection time? will this mod shorten the turbo and engine life? also i run a diablo sport predator........thought u might have answers to these questions, since u seem pretty knowledgeable about this subject...........

To get a significant increase in whistle you need to lose the cat. I have the MBRP turbo back system - but only the catback portion installed right now. My turbo whistle is only a little louder than stock, and I have noticed no increase in performance - just a nice reduction in egt's, and a nice exhaust note under hard acceleration.
A catback stands a far lesser chance of voiding your warranty than a turbo back.
No, the catback will not hamper with emission testing, and no, a catback will not shorten the life of your turbo.
Finally, do yourself a favor and ditch the Predator for SCT or Quadzilla, your head gaskets will love you for it!
