Definitely like the change in the rear look of the car with the added diffuser and the exhaust.
For appearances my decision has been to stick with the black sport grilles and the black rear diffuser. I've added the CF mirrors and the CF Performance spoiler will go on the car Monday. Last I will add the CF Performance splitter and that will be all the changes I'll do for aerodynamics and outside looks. I considered adding the ///M "type" spoiler and mirror caps, but in the end decided to keep the car's look M Sport / M Performance parts because it's not an ///M.
Speaking of ///Ms last Saturday we participated in a Toy Run / drive. Here's some video of that.
