exhaust backpressure?

I'm new to the forum. I have a 07 f250 6.0l and wanting to install a cat back system. My question is, will the loss of backpressure in exhaust effect the turbo function. Am I understanding the engine needs some backpressure for the sensors to work right to control the turbo.

I have another question about the flutter when you let off the gas. I noticed it at 900 miles. It seems to do it when I'm cruising about 60mph and let off. Kinda sounds like a exhaust brake, but can tell it is something to do with the turbo. Is this normal or does the dealer need to fix something? Will installing a cat back system help this flutter problem?

you dont need to worry if your just doing a cat back exhaust, the cat will provide plenty of back pressure

That noise your hearing is completely normal. I can make any 6.0 do it and if you have an open air filter it is usually more prominant

i wont get technical unfortunately (others might help with that) however you should be fine with cat back only. some on the forum will tell you they have had problems with no muffler and others like myself have had no problem with no muffler. imo they do need some backpressure.
the sound your hearing is normal. search threads for that and you will find an explanation.
by the way, welcome!

What's back pressure?
Just kidding! Welcome to Powerstroke.org!
My '05 is straight piped so those who tell everyone the 6.0 needs back pressure need to explain to me why mine doesn't need back pressure and runs like a raped ape.

Alan...call Mythbuster on this one. Maybe you can get your truck on the Discovery Channel! Then again they usually blow things up by the end of the show!

Let me put a differant light on this. The exhaust systems we sell for the 6.0l 9 out of 10 times is a turbo back system with a cat delete and muffler delete. Have never once had a customer call me with a problem. Is it luck? Maybe, but thats alot of luck!

Thanks Scott!
Yeah I ought to Pat - I love that show. Especially when they beat the crap out of that crash dummy.
There are a lot of us on here who are straight piped 6.0's with no problems and flat out loving it. I really don't think I've ever heard of someone who was straight piped and had to go back because they had problems.
