M/C air cleaners?

[Truckedup]

 I see nothing mentioned about flame arresters or airfilters . So it's legal to run open velocity stacks ?

[Stainless1]

yes and open pipes


Production will require the pipe look stock and the intake remain the same size

7.E.1 states clearly the intake air box must be identical to the production model...air cleaner element may be removed. I believe you could modify the backplate, but it must appear stock in view. Exhaust opening cannot be enlarged, but internal modifications would be out of view.
