I purchased a set of ICW Kobe wheels, 15 inch ones btw, I am trying to keep my tire costs down, and DTM 3.5 inch muffler. The muffler came from overstock.com and the wheels are from a site called
Car rims, Custom Wheels Tires, OEM wheels, Truck Rims, Chrome Rims , I also have a set of sport visors on the way too.

And like always pictures and video clips will be uploaded. And yes, I am changing out the piping so its a cat back setup. It will remain at stock diameter which is 2.25 inches. The wheels cost me $354 shipped to my front door and the muffler was $75.
Here is a picture of the wheels, and a picture of the muffler.
