back pressure

[shaggy337]

Im hearing that the 6.0ls need some back pressure. Is this true or a bunch of BS. Im trying to 5" striaght pipe my stocker 07. If anyone knows anything please post away.

My exhaust right now dead ends at the end of the cab no CEL.

You didnt see anything wrong with it, was it running differently? and yours is pretty close to stock

[westcoaststrokin]

Yep no problems just have to go out this weekend and instal the muf delete so I don't rot the bed and all will be good.

unless your planning on alot of big HP mods the 5" is over kill, I'm straight piped and felt a loss in the bottom end stock

yes this is true to an extent. if you are running STOCK programming, you will lose a little bit of low end, and gain some in the higher rpms.

if you running a programmer or have major mods, you will see gains throughout.

I installed a straight pipe on my 6 O a few weeks ago and I am not sure about the loss of low end power, i don't feel none, but now it takes off from a dead stop a lot quicker due to less turbo lag. I feel that it has more power, but that might just be the sound. Don't really see why you would need back pressure anyway.
I'm pretty low on the posts, like 1, but i'm speaking from my own experience. Good Luck

yes true. the general rule is that on a turbocharged vehicle, the turbo should be all the backpressure you want, and this holds true to an extent. like i say, straight piping it just moves your powerband up a bit and that's where you will see benefits.
this is with a stock truck i've been told by several people, HOWEVER, i am not running a stock truck, so the straightpipe was a no brainer.
