Point the opening toward the outside of the vehicle, away from fuel and brake lines, so exhaust doesn't collect under the car. For the best sound, mount it after the X-pipe or H-pipe. Because you remove the block-off plate by hand, choose a spot you can reach easily.\u003c\/p\u003e\u003chr\u003e\u003ch3 style=\"margin-bottom:10px; color:#666666;\"\u003eLegal Note\u003c\/h3\u003e\u003cp\u003eMany states, including California, prohibit exhaust cutouts on vehicles driven on public roads.
