Installation of MBRP Installer Series Resonator Delete X-pipe (15-19 GT)

1. Lay the Resonator Delete Assembly on top of the OEM Cat Back being sure the inlets are aligned with each other. Note that the passenger-side outlet has more bend angle than the driver-side outlet. Transfer marks or use tape from the end of the Resonator Delete Assembly to the OEM Catback. 

2. Measure 2” forward of the marks made in step 1 and scribe a cut line on the OEM pipes. The cut lines should be at the end of the straight section of pipe right next to the bends exiting the OEM Resonator. Using a Sawzall or similar tool, cut and deburr the OEM pipes with a file.

3. Reusing the original clamps, install the Resonator Delete Assembly being sure that the outlet with more bend angle is located on the passenger side of the car. Ensure the Assembly is installed level as viewed from the rear and tighten the clamps.
4. Install a 2.5” Clamp onto the passenger side outlet of the Resonator Delete Assembly. Reinstall the passenger-side of the OEM catback using the previously removed mid and rear hanger brackets.
5. Reinstall the driver-side of the OEM catback using the same mentioned procedure
6. Install the undercar brace [Convertible Only] using the previously removed hardware.
