I went to the dealer for my sunday morning drive today. They had 2 CSs on the lot(heavily discounted 07s) with the factory round pipes. I was NOT impressed with the finish quality around the area where the chrome stops around the edge of the pipes. It is just my taste but I also do not care for the ridges at the edges of the pipes as opposed to the smooth finish I saw on the BMWs on the lot next door. Do they serve any purpose? I intend to call Boothe on monday morning.
