I had to sign an EPA and DBA agreement stating I understand that this isn't a road legal exhaust due to emissions and noise levels. It works in tandem with the ANIMA switch which is awesome. Aftermarket systems are either open valves at all times or you have a goofy plastic remote to open and close valves.

Race exhaust costed me 13k installed. It isn't titanium, isn't that much lighter, about 5-10hp more. There is a pamphlet that has the official figures. For that OEM feel I recommend it, the sound is unmatched. Granted there are very few exhausts on the market at the moment. If I had to choose, I would do a Tubi or Akrapovic above the rest...assuming they get made.
