Default Thunderheader fitment question?
Will a Thunderheader off of a 2002 Softail Heritage fit a 1999 Fatboy?

from what I’ve seen on the website it says they will but don’t know how to be 100% sure

Many times with these kinds of questions you can go to DK or J&P, find an aftermarket exhaust that fits one of the models you listed then look at the fitment guide and see if the other model is listed. If the aftermarket exhaust lists both there's a very good chance that it will fit.

Yup, you'd think so but he had a problem with the Heritage foot board mounts with the earlier TH he picked up.

Correct. A header off of a 91 Springer “Softail” did not fit on my Fatboy.

the heritage floor setup should be the same as Fatboy correct?

As far as I know the only thunder header for a softail looks like this one.. Single pipe in the front not the 2 wrap around the nose cone pipes... I could be wrong but.......
