I could se this at +- 10mph or less, but travel down a gravel logging road at 25-30 I'm not seeing that the exhaust is kicking up dust that gets inside the cab.

The dirt and dust from the tires rotating that fast must be hundreds of times the level of dust that the exhaust can cause.

I also have a rancher friend with a Polaris that uses the "stealth exhaust" which he has going out to the side, not down. His dust issues are no different then mine.

The air intake inside the cab is for the transmission. I cannot see even see a minuscule level of suction that would generate a vaccuum of dust while driving or even parked for that matter from the air intake!

I'm not aerodynamics engineer, could be all wrong on this, but I just don't see from a logical standpoint that the direction of the exhaust above 10mph, or the transmission air intake are involved.
