The sound in the cab is definate. I know they are there. But since it is usaully just me, I don't mind. Hower, my wife says it sounds like a need a muffler. I tell her if she doesn't like it, then she can meet me at our destination in her car.
I have no time for a women who can't accept what I appreciate.
As for the departure angle. Well it is pretty easy to see that I loose it with this particular Mod. Like I mentined before, it isn't going to go off road, so the pipes are no big issue on this truck.
