Colony Exhaust Stud and Nut Kit for Harley Davidson

Including 4 studs and 4 hex nuts.
Mount the exhaust on the cylinder heads.
Note: The exhaust studs used on the M8 engine (OEM 10900015) are a slightly different design, with a small hex shaped outer end sticking out to make initial installation of the studs easier, but these early Evo/Twin Cam style studs will still fit.
