Exhaust
Hi
I have an 04 6.0 cc long bed and bought an exhaust cutoff for it because I can keep it quiet when I want to or have it loud. I was talking to a friend of mine and said that having a cutoff may ruin the turbo because the turbo works off of back pressure or something like that. I was wondering if I put it right before the muffler if it will hurt anything. Also when I took off the cat I drove around for fun with straight pipe and the turbo fluttered like crazy. I know they do that once and a while but is it bad doing it all the time.
Thanks

So basically it will be a good thing for the engine. And the turbo flutter is nothing. My friend was saying that the turbo is meant to work with that length of exhaust and cutting it in half could cause problems.

The sooner the exhaust gasses gets out of the pipe...the better. A pipe out the hood of the truck isn't exactly pleasant looking (or at least my book). If you could get away with it...the turbo would be happy if there was nothing attached to the exhaust side of the exhaust housing. We're not talking about a 2-cycle gasser or Detroit that needs the exhaust scavenging to move the gases through the engine.

I had a guy at a muffler shop the other day try to tell me I was hurting my engine and killing my mpg by running striaght pipe. He said that a flowmaster muffler then 4inch exhaust from there back would actually flow better than my 3.5 inch straight. Because the muffler creates a vaccum and makes the exhaust flow faster. I think he was just trying to sell a muffler.
My 04 F350 DRW 4x4 crew cab chassi cab sounds good and has plenty of power. I was just wanting to add another tail pipe to have duals. He told me I would have to buy a programmer to be able to run duals. I just love the sound and wanted it on both sides.

. Either he's an idiot or trying to be crafty...or a little bit of both. The only reason you'd need to run a tuner/different tune is if the EGR has been taken out of the equation.

I figured he was just wanting to sell a muffler.
I would like to add a tuner but I have heard so many people that have had trouble after doing it with their 6.0 My powerstroke is already on its third turbo, had the bed plate seal replaced and alot of little crap that kept in the shop. Other than little engine problems my biggest thing is limited slip clutches. I had the limited slip pack replaced once by Ford but I just replaced it again with an aftermarket unit this week. That was a quick $1200. But this unit doesn't have clutches to wear out it has gears in it. Suppose to be better. My truck is a work truck and thats what she does 99% of the time. Either hualing hay, equipment or anything else that will fit on my trailers.
I know my exhuast temps had to be lowered when hauling by taking the muffler and cat off. I always let her idle while I am unchaining or unstrapping the load. Years of letting my agri tractors idle to cool turbos has made this a habbit. I would like to add a dual tail pipe setup on it one day. I just don't want to buy a tuner and have to replace head bolts because mine failed. I was told that is the weak link on the 6.0 after turbos and bed plate leaks.
