Why? It's not impeding anything, and if you think you're going to get that magic 1 extra horsepower that's going to turn your Jeep into a racecar, I'd advise laying off the paintchips.
Stupid shit like "I pulled one over on 'The Man' by hollowing out my cat" doesn't do ANYTHING to help our cause in keeping access to the roads and trails. That's a FINE example you're providing to those who want to close off the National Forests and public roads to four-wheel drive use. Because of examples and lemmings like this, it undermines our argument that Jeepers and other four-wheelers are environmentally responsible.
Yes, I said "public roads" because 'round these parts, most of the "trails" we enjoy are actually roads that have existed a hundred years or more. So we're really not "going off-road" as much as making use of existing rights-of-way.
Do your bit to keep your tailpipe emissions lower.
