Does your state do emmissions tests and annual inspections? If you answered yes to either part of that don't do it. You'll fail inspection and not be able to "legally" enjoy your car until it is corrected.
lol! If you gotta bust out a sawzall every time you go for inspection that is gonna be a pain. After a couple years your exhaust will be 6" shorter.I might look into... its not work with a saws-all and a piece of staright pipe.........
