On the top of everything, my car has warranty, and i don't want to find out one day that my warranty was void because of some innocent exhaust tip change.
my dealer advised me to do my 4 quad tips from borla and plug the vacuum line, wont mess with warranty or performance, they even checked it all out and said it was fine, looks so much better, and fits nice in the stock diffuser. The chrome always got black, these are stainless and easier to clean, one member here powder coated his tips the same color as his car, I didnt think I would like the rear spoiler at first but I love it, $300. from dealer, also the same with the black grills, I love them, I also had the small silver fins in the front painted black by my shop also.
