I got a great deal on amazon for some cats/downpipes for $390, but when I went to put on the header flange gasket, it wouldn't fit. I measured the pipe OD and its 2 1/4, the stock is 2 1/8" I called Magnaflow and they said the OD is supposed to be 2.1". I tried to return them, but the 2 pipes/cats were sent by separate shops and one says they are correct and the checked with Magnaflow. Beware amazon, make sure they shops have been there for >2 years with positive feedback. the shop name is Performance Exhaust Specialists. Can I use these? its going to be $83 to return them, hardly worth it, even for a full discount. Does anyone know of a flat flange gasket I can get?
