Anyone out there have a stock set of "slinkys" who could measure their lengths in the extended position? I think I have 2 fronts, and I want to cut one back to fit the rear exhaust pipe on my rigid frame panhead. Any help would be appreciated.

I notice you haven't had any replies, so I've got to figure no one has a stock set. Personally, I would just cut the rear to fit the pipe, as I believe there can be extenuating factors that would make for variable applications. I think the best solution would be to study period photos, and count the number of coils, or note the appearance of the coils at various bends in the pipe.Eric Smith

The length of the front differs between Panheads and Knuckleheads because of the different placement of the pipe to frame clamp.Be sure to visit;

Thanks Chris and Eric for your replies. Your idea to count the coils is a good one Eric. And yes, Chris, the front would be shorter for I believe pre-'47 because of the front pipe clamp placement.Comment

Short fronts also are used with a sidecar. Rears differ from Pan to Knuckle due to the pipe bell, etc.Robbie Knight Amca #2736Comment
