exhaust gasket question

[theblue]

so I'm replacing my mid pipe gaskets and bolts since they are shot.

I'm confused about one thing on real oem. do I need one of part 23 and 24 for each side, or do I just get part 23 x 2 (for each pipe)?

need one of each; look closely at the diagram. slightly differ in size. :-)

gotcha... thanks.. wasn't sure if one was a replacement part for the other.
