Legality of exhaust wrap?

[Aracheon]

From the rule book:

14. Exhaust systems.
a. Wrapping of exhaust systems is prohibited, except in the area of
the rider's foot for protection from heat.

There is a link to the rule book on the main mra-racing.org page if you want to look through it further.

How in the hell did I miss that?

I guess maybe I'll learn how to read first... thanks man.
