This Resonator Delete X-Pipe from Ford Racing will fit all 2015 GT Mustangs.
The resonator on your new 2015 Mustang GT is big, heavy and restrictive, which is a horrible combination for a performance vehicle. There are a lot of options that you can pursue to replace it, but the most cost effective might be the Ford Racing GT Resonator Delete X-Pipe. This product simply bolts in and upgrades the flow of your exhaust, the performance of your vehicle, and gives it a true Mustang sound.

1. To start the installation of your new Mustang Ford Racing M-5251-M8 Resonator Delete X-Pipe, safely lift the vehicle either with a lift or a jack and jack stands. This installation will utilize a jack and jack stands.
2. Begin by loosening the bolts holding the exhaust hangers near the Mustang differential with a 13mm socket.
3. Lift up on the Mustang exhaust hangers to unhook them from the subframe.
4. While at the rear of the vehicle, take rags and stuff them between the top of the Mustang exhaust tips and the rear valence. This will help to protect the tips from being scratched when dropping the exhaust.
5. Loosen the bolts to the front clamps of the resonator with a 15mm socket.
6. Using a flat head screw driver, lift on the front of the clamp to clear the stud. Proceed to slide the clamp back as far as possible by hand.
7. Place a jack under the resonator. This will help to keep the exhaust from dropping to the floor. Slide the resonator back and lower to the ground. Pull the jack out from under the resonator.
8. Measure 4 inches from the rear of the resonator and draw a line on each pipe. Repeat for the other side.
9. Place the jack under the existing Mustang exhaust. This will help to keep the pipe from collapsing on your cut, therefore kicking your sawzall out. Proceed to make both cuts. File the edges of the fresh cut pipes.
10. Pull the resonator out from under the vehicle. Pull the clamps off the front.
11. Place the clamps on the piping coming from the front. Push on until they are over the studs.
12. Pull the new Ford Racing clamps out of the packaging. Disassemble the end as shown.
13. Pull the end around and reassemble, leaving the nuts loose.
14. Slide the Mustang X-pipe into position. Use the hammer to tap the end of the X-pipe to ensure it is fully seated. Slide the new clamps onto the end of the pipe. Lift up on X-pipe and existing piping, then slide the clamps into position. Use a jack if you need assistance lifting everything into position. Reinstall the rear exhaust hangers into the subframe.
15. Snug the nuts down for the front clamps and new rear clamps. Torque the front clamps to 40 ft./lbs, and the rears to 35 ft./lbs. Go through the entire system, aligning it along the way to ensure proper alignment of the tips at the rear valance.
16. Remove the rags at the tips, lower the car the ground, and enjoy your new Mustang Ford Racing Resonator Delete X-Pipe. Re-torque all of the clamps after 5 heat cycles.
