How to Install a Magnaflow Dual Catback Exhaust on Your 2010 Mustang V6

Warning: When working on, under, or around any vehicle exercise caution. Please allow the vehicles exhaust system to cool before removal, as exhaust system temperatures can cause severe burns. If working without a lift, always consult vehicle manual for correct lifting specifications. Always wear safety glasses and ensure a safe work area. Serious injury or death could occur if safety measures are not followed.

Step 1: (Carefully read all instructions before installation) Disconnect the vehicles battery before removal of the OEM exhaust. This will allow the computer to reset itself with the new system, and prevent electrical accidents.

Step 2: To remove the OEM exhaust system locate and remove the clamp rear of the stock mid Y-pipe. Working front to rear loosen clamps and remove hangers from rubber insulators. retain all mounting hardware as it will be needed for installation of your new MAGNAFLOW system.

Step 3: **Carefully cut out the profile of the paper cutout template from the hardware kit. Tape the template to the rear bumper of your vehicle using the 4 edges for orientation as shown in fig #1. Mark the profile and cut out the tip cutout. Remove rough edges.

Step 4: Install the OEM rear-muffler bracket on the hanger of the new passenger side muffler assembly, and install the OEM front muffler bracket on the driver side muffler assembly. Fasten the Y-pipe assembly to the catalytic converter re using the OEM clamp. Leave all clamps and fasteners loose for final adjustment of the complete system. Install the new over axle pipes using the supplied 2.50" clamps. Install the muffler assemblies using the supplied clamps, and by bolting the mount brackets to the frame using the OEM fasteners. See fig #3 for more detail on mounting the passenger side muffler.

Step 5: With all components mounted loosely, adjust the system for overall aesthetics and clearance of frame and bodywork. (MAGNAFLOW recommends at least 1/2" of clearance to prevent heat related body damage or fire)

Step 6: Once a final position has been chosen for the new system, evenly tighten all fasteners from front to rear. The supplied band clamps must be very tight to properly align the pipes and prevent leaks (Approx. 65ft-lbs). U-bolt clamps should be tighted to approx. 30-35ft-lbs. Inspect all fasteners after 25-50 miles of operation and retighten if necessary.

**MAGNAFLOW strongly recommends professional installation, and any cutting or modifying of the valence or fascia should be conducted at your own risk.
