I got a new 2007 GMC Duramx 2500hd
What's the deal with the exhaust
Is there something you can do with the big can out the back
Is there a leveling kit for the front end
Suggested mods
what is the difference on the engine code everyone is referring to

I'm wondering the same thing! I love the new body styles, but I will have to add a leveling kit for sure and probably just get used to the new look of the oversized exhaust pipe sticking out the back end when I get mine. The warranty is void on the powertrain, I think, for removing the system due to the new governmental regulations. I love to see anyone's comments on the leveling kit if there are any.

Y=00

yes you can lift the front end with the T/Bars but it will affect the ride slightly but not really that noticable..
