It's only a 15 min job to remove and put on mid pipes, I got the catted one sitting in the garage and the X on the car and I got a cool dealership in town so the only time i'll need to put it back on is a day or so before smog
what exactly are you talking about? hes asking when u get your car inspected how do you pass emssions...
i live in sunny FL so no car inspections or any of that nonsense.
its pretty easy to switch out your exhausts if you want to.... i went w/ a Dr. Gas O/R x-pipe that pipe needs welding so it isnt going anywhere.... theres been discussions on this before try searching for "no cat emssion test" or something along those lines...
