Whats this movie called?

[Panther]

I am looking for the name of a movie I saw many years ago and would like to check it out again, but I remember very little about it. This is all I remember, pretty sure its from ´70 something, its about two stuntman that do all these crazy things and do a big carjump in the end over a canyon or something. So if anybody recognize these tuffguys please say whats this movie is called, I am going crazy trying to find the name...
