Reply To: Who has de-cat experience? May 5, 2019 at 2:11 am #4863 QwandreeModerator I have the Leo Vince link pipe with the stock exhaust (baffles in). You don’t need to do an ecu adaptation. For me the sound is perfect. Much much better than with the cat. Throatier and not too loud at all. Some popping on decel… I love that, some don’t. There’s maybe a hair better engine performance. Huge weight savings is the real reason to do it. The better sound is gravy.
