5. Remove exhaust mid pipe by removing band clamp from y pipe(15mm)

6. After all exhaust piping is removed hold the x pipe up to the y-pipe and mark where the y-pipe needs to be cut.

7. Cut y-pipe with pneumatic air saw while wearing a face shield for safety.

8. Fit x-pipe to fit behind the catalytic converters and put clamps on but do not tighten all the way just so that they stay on and in place.

11. Make sure muffler tip and box is lined up correctly and is straight.

25. Take for short test drive to make sure nothing is rattling around and that there are no noises being made from underneath the car.

27. After that enjoy your new dual exhaust for your V-6 mustang.
