Just did the Borla Stingers. Great sound!!!!! I didn't want my stock exhaust so I cut mine off. Who wants a stock exhaust?? Wrong car for that! Anyway, if you do want to save your exhaust then you will have to be able to lift the car about 3 feet. NOW, if you don't want to save em, then listen up, I scribed two lines where I was going to cut the pipes in case I wanted to go back to stock, then I got under the car, rear on ramps, cut the pipes in two, just where it starts to make the bend to go over the rear, hold muffler weight up. I used my big toe, otherwise, pipe will bind when you cut through, breaking blade (don't ask how I know this) Then you have to take the pipe out towards the back of the car (easiest way) you need a floor jack to lift the body a couple of inches when you are taking the pipes out, leaving the tires on the ramps, lift body, pipe will come right out. Then do other side the same way. Borla's come in pieces, put on loose, I tightened at front clamp. Took a level, touched all four tips, tightened everything up, checked tips again, run for a few days, check tips again......your done! Congratulations, you did a fine job, thank you.....bob.
