I think the new exhaust looks great and congrats on being the first I have seen to have the balls to go for it! I assume you do not have the Add-Blue connected to your set up. How will that effect emissions and warranty? I would love to see the look on the Mechanics face when you take it to the shop for the next oil change!
What's next??? Custom Intake??? After that sick exhaust I can't imagine what kind of intake you are going to come up with.
