Gasket used on both ends of the factory midpipe when used with the factory muffler and downpipe. Used on all NBs with both manual and automatic transmissions. Two per car.

MSM fitment note: this gasket is not used between the factory downpipe and midpipe, it is only used between the midpipe and muffler on that car. One per car in this case.
