Exhaust Muffler

Schematic: F-15 Exhaust Muffler
Affected/related parts: Frame and Right crankcase cover (determine mount points), Cylinder head (determines angle of header)


The Exhaust Timeline:

#1) 18300-028-000 - Very Early 2 piece, 2 tab on top, 45 degree header

#2) 18300-028-010 - Early 2 piece, stud mount to frame + forward tab mount to crankcase, 45 degree header

(*the magic switch from part 18200-028-000 45-degree header to 18200-028-010 90-degree happens here at frame serial number 527510)

#3) 18300-028-010 - Late 2 piece, stud mount to frame + forward tab mount to crankcase, 90 degree header

#4) 18300-028-020 - Late 1 piece, 1 stud mount, 90 degree header

#5) 18300-028-670 - Very late, 1 piece, 2 stud mount, 90 degree header





#1) Very Early, 2 piece, 2 tab on top











#2) 2 piece, 1 stud to frame and forward tab to engine


*Note the stud (circled in blue) that mounts to the frame.  The forward mount (circled in red) is the attachment point to the engine.






#4) Late, 1 piece, 1 stud mount with 90 degree header






#5) Very Late, 1 piece, 2 stud mount with 90 degree header












Variation: Header Angle
  • Parts Number(s):
    • Late style 90-degree header [top] = 18200-028-010
    • Early style 45-degree header [bottom] = 18200-028-000
