That's about how I found it. Got under it with a flashlight after it had cooled down put my hand up around the bellow and got someone to crank it got it up to around 2000rpm and could feel the exhaust blowing

Truck runs good and the black spot hasn't gotten worse but this worries me. How major is a minor crack or leak? Long term affect? Covered under warranty?

I lie this site but daggum it makes me paranoid. Fml

From what I understand, it's not a huge deal. A small leak isn't catastrophic, but it will get worse as the pipes heat and cool. I drove with a crack in mine for a month and it started small. While towing my work trailer, it gave out, cracked all the way. Truck still ran but had very little boost and was pouring soot out the hood!

One more question for you gentlemen. What causes this to happen. I've read its from back pressure. And should I go ahead and replace them both

I just had a bunch of work done to mine and while the cab was off we noticed the drivers side up pipe was blown. The passenger side was fine. The shop charged me $150 for the pipe.

I've been hearing a hissing noise that gets pretty loud and my boost seems really loose like its pouring out of a leak somewhere. I'm tuned and running the HD300, and I keep defueling when I accelerate because of too much boost. Does this sound like the same problem you guys had? I'm at work now or else I would go take a look at it.

[fiderius22]

I never defueled. I run a mini with hd 300 as well. I was short on boost when mine went but take a look at yours. I might also look at the upper and lower intercooler boots. Down pipe also. Not sure.

Its a bear to do cab on, plan on having it apart for a few days if your doing it that way. Other wise I would use your buddies lift if you can.

I had a hissing noise coming from the driver side of my truck and it ended up being the down pipe to the egr cooler was cracked at the bellow (because i had a delete and never made a bracket to hold the pipe from bouncing up and down). So that might be something to look at if your deleted.
