Hi Guys, So the car is long gone, but I just came across a box labeled 328 Cats. Does anyone have a use for these? They were taken off Dad's 328 a number of years ago. Thanks
The 328 only has one cat, and the OEM cat really isn’t anything to write home about. Unless someone is overly concerned with originality or looking for a very detailed Classiche certification, Hyperflow or Fabspeed are better options from a performance standpoint.
