Topic: 4 into 1 exhausts allowed in AHRMA F750 class?

[gschuld]

I recall in the Big Benly article that they started off with a Yoshimura copy exhaust in the late 1990s but after a rules change they were forced to built a 4 into 4 instead.

Has that been repealed?  I assume so, as I didn’t see any mention of it in the newer rules anyway

For AHRMA the only rule I can find is 9.7.13.

Exhaust Systems

a) Period-style exhaust systems are encouraged.
