Last Updated April 16, 2024 | Bill Tumas

How to Delete the Resonator on Your 2024 Mustang

In this guide, we'll walk you through the process of removing the stock resonator on the S650 Mustang and replacing it with a MBRP resonator delete X-pipe. We're performing this install on a 2024 Mustang GT with active exhaust, but the process is largely the same if you have one without active exhaust. With a few basic tools and a reciprocating saw you can delete the resonator on your 2024 Mustang for a customized exhaust tone.

Check out the video below for more information on the installation.

Tools Needed

  • 3/8" Ratchet
  • 7MM Socket
  • 13MM Socket
  • 15MM Socket
  • Reciprocating Saw
  • Marker
  • Safety Glasses
  • Flat-head Screwdriver
  • Tape Measure
  • Metal File

Step 1: Remove the Rear Belly Pan

The S650 Mustang has new, extended belly pans on the underside of the chassis that make it hard to access some areas. Remove the rear belly pan underneath the cat-back to get proper access to your exhaust.

Step 2: Disconnect the Factory Wiring Harness (Optional)

If you have a factory active exhaust model, disconnect the wiring harness on the factory actuator. If you don't have active exhaust, skip this step.

Step 3: Disconnect Push Pins (Optional)

Then, disconnect the factory push pins holding the wiring harness to the assembly. This can be skipped if you don't have active exhaust.

Step 7: Remove the Exhaust

This can be done by one person, but it's much easier with an extra pair of hands to help. Slide the whole of the exhaust towards the rear of the vehicle. Then, gently lower it until it's complete detached and able to be dropped.

Step 8: Mark Your Cuts

Line up the resonator-delete X-pipe with the front of your stock exhaust. Ensure that the angled section of the X-pipe is aligned with the angled section of the stock exhaust, then make a small mark where the two ends meet.

Then, following the directions provided with your X-pipe, measure two inches towards the front of the stock exhaust and mark it. This will be where you cut the exhaust pipe.
