Default Grand Am Update New Exhaust

I have been working on the car for the last month or so and made some progress. I changed the exhaust system. I had dual 3" cats reducing to 2.5" all the way back. I decided to buy a 3" Dr. Gas X-Pipe kit and the exhaust is now 3" to the mufflers, then tapers to 2.5" over the axle. I didn't see the need for 3" over the axle, and don't want the noise. The system now uses V-Band clamps which I really like, and looks much cleaner. The entire sytem is being ceramic coated to match the headers with a dark charcoal color. These are pictures of the mock up.
