1. Using a lift place the car in the air.
2. Disconnect the (4) 02/Wideband sensors at the connectors.
3. Place a pole jack under the resonator to support the exhaust while you work on it.
4. Using a 3/8" ratchet with extension and 15mm swivel socket loosen and remove the (4) nuts which hold the factory pipe to the manifold.
5. Using a 15mm socket loosen the (4) bolts on the band clamps located just before the resonator.
6. Once loose tap the band clamps towards the rear of the car with a rubber mallet.
7. Remove the driver and passenger side legs.
8. Using a 7/8" wrench remove the front and rear 02 sensors from the factory pipes and swap them to the Lethal Performance midpipe legs. Make sure to place the front sensors from the stock pipe onto the front sensor locations and the rear sensors from the stock pipe on the rear sensor locations on the new pipe.
9. Measure 7" from the weld on the underside of the resonator and mark it.
10. Using a sawzall cut the pipe straight at each 7" mark. Make sure to wear safety glasses and have a helping hand hold the resonator from moving around while cutting.
11. Using a file clean up the burrs created when you cut the factory pipe. This will make putting the band clamps on much easier.
12. Re-install the driver and passenger side legs onto the factory manifold leaving the nuts loose so that you can adjust them later on.
13. Reconnect the 4 sensors to the factory harness.
14. Take the factory 2.25" band clamps that were removed from the front of the resonator and put them on the piping which leads to the mufflers.
15. Use the supplied 2.50" band clamps and instal them on the aftermarket legs.
16. Place the H-pipe resonator delete in place. The bent leg on the rear of the h pipe resonator delete should be aiming at the passenger side rear wheel.
17. Slide the band clamps into place so it secures the H-pipe.
18. With a helping hand you'll have someone hold the mufflers up in place making sure the mufflers and tips are where you want them. Then tighten the (4) nuts that hold the legs to the exhaust manifolds. Then proceed to work back to the clamps in front of and behind the resonator delete H-pipe.
Huge thanks goes out to Donnie at Power by the Hour Performance for helping out with the install. Thanks man!
