In the later model years, it seems that if youre not careful, you can lose some torque if you dont keep some back pressure. I would go with a performance muffler for this reason. But, folks with flowmaster on a 2004+ truck are losing torque with the muffler, and gaining power with a magnaflow which is vitually free flowing and see through.
Longer story short, If i was you, Id get the glasspacks. You have already heard what they will sound like. Plus you like it, and its inexpensive. Also, I think you have already made up your mind, but just need a little nudge. Get the glasspacks and enjoy your truck!
Oh yeah... You might get one or two mpg increase(if you can keep your foot out of it) and a little out of the butt dyno. You shouldnt have to worry bout any damage. Now go get em!
