And, unlike every other mod you do to your Jeep, this thing does NOT decrease your gas mileage! Before and after the mod, you can be assured that your gas mileage will be totally, completely, one hundred percent of what it was before this exciting modification!

 

No, it will be less because you're adding weight.

On second thought, your wallet will be lighter by the same amount, so it offsets.

 

$1 Whistle will not offset the weight to dollar ratio because the gain is so insignificant.

 

Joke thread... lol

 

Yes, but you overlook that when you drive down the road to the mailbox to send your payment away, you will wear down your tires. That will offset the weight of the dollar. It will also serve to further lighten your wallet, both by the wear/tear on those tires (must be replaced earlier), and by the gas consumption.
