Dam, if I don't just keep coming up with more things to do. My Black 300C has 652 miles and I have the "Bentley" grill and thought I only needed tinted windows and 20's. Add to the list the extended exhaust tips. Not a gear head so work with me....do you have to swap out your entire exhaust system...or can I somehow add the tips to simply supply the more visible tips? One thing I don't like is you can barely see the dual exhaust and the extended tips are a must. Any feedback is much appreciated.
