Product Information

The product is the 2023+ Sequoia Overland exhaust system by MagnaFlow. It consists of various components that are listed below:

  • Inlet D/S Assy.
  • Inlet P/S Assy.
  • Muffler Assy.
  • Midpipe Assy.
  • NDT Resonator
  • Pipe Cap
  • Overaxle Assy.
  • Tailpipe Assy.

The product also includes a hardware kit with the following items:

  • [3] 2.50 Clamp
  • [3] 3.00 Clamp
  • [1] MF Block Off Pipe

Product Usage Instructions

Before installing the product, it is recommended to read the instructions thoroughly and take necessary safety precautions. The following tools are required for installation:

  • 13mm and 15mm wrenches
  • Hanger Tool (or Pry Bar)

To ease the removal of existing exhaust components, especially on older vehicles, spray penetrating lubricant on all fasteners and hangers/insulators that will be loosened or removed. Let it soak before disassembly.
WARNING: Exercise caution when working on or around the vehicle. Allow the vehicle’s exhaust system to cool before removal to avoid severe burns. Always consult the vehicle manual for correct lifting specifications if working without a lift. Wear safety glasses and ensure a safe work area to prevent serious injury or death.
ATTENTION: When installing the supplied band or U-bolt clamps, tighten them to the proper torque specifications. Band clamps should be tightened to 40-45 ft-lb, and U-bolt clamps should be tightened to 30-35 ft-lb. Over- tightening may cause clamps to break and will not be warranted by MagnaFlow.

Follow the steps below for installation:

Step 1: To remove the OE exhaust system, loosen fasteners at the inlet flanges where they connect to the catalytic converters. Disengage the hangers from the rubber isolators, remove the remaining fasteners at flange junctions, and drop the system. Retain the inlet fasteners, gaskets, and rubber isolators for installation of the new system.
Step 2: Begin installation of the new MagnaFlow system by attaching the Passenger Side inlet first, followed by the Driver Side/Y-Pipe Assembly. Use factory hardware to attach the flanges and a provided 2.50 TORCA clamp to attach the passenger side inlet to the Y-Pipe.
Step 3: Slide the Muffler Assembly into the outlet of the Y-Pipe and fasten the hanger to the rubber factory isolators. Loosely tighten a 3.00 TORCA clamp to hold the muffler in place.
Step 4: Install the Over-Axle Pipe. Slide a 3 TORCA clamp on the muffler outlet and loosely tighten to hold it in place. Also, attach the hangers to the factory isolators.
Step 5: Install the Helmholtz J-Pipe using a 2.50 TORCA Clamp. Cap the end using the provided MF label Cap, also with a 2.50 TORCA clamp.
Step 6: Lastly, install the tailpipe resonator assembly utilizing a 3.00 TORCA clamp. From rear to front, tighten the entire assembly. Be sure to re- tighten after the first 100 miles once all components have been properly heat cycled.

MINIMUM REQUIRED TOOLS

MAGNAFLOW RECOMMENDS PROFESSIONAL INSTALLATION ON ALL THEIR PRODUCTS

  • WARNING : When working on, under, or around any vehicle exercise caution. Please allow the vehicle’s exhaust system to cool before removal, as exhaust system temperatures may 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.
  • ATTENTION : Always install any supplied band or U-bolt clamps to the proper torque specifications of 40-45 ft-lb for band clamps and 30-35 ft-lb for U-bolt clamps. Over tightening will result in the clamps breaking and will NOT be warranted by MagnaFlow

INSTALLATION

  1. Step 1. To remove the OE exhaust system, loosen fasteners at the inlet flanges (2) where they connect to the catalystic converters. Working front to rear disengage the hangers from the rubber isolators, remove the remaining fasteners at flange junctions, and drop the system. (Retain the inlet fasterners, gaskets, and rubber insolators, as they will be used to install your new system.MAGNAFLOW-2023-Sequoia-Overland-FIG- \(5\)
  2. Step 2. Begin installation of the new MagnaFlow system by attaching the Passenger Side inlet first, followed by the Driver Side/Y-Pipe Assembly. Use factory hardware to attach the flanges together, and a provided 2.50″ TORCA clamp to attach the passenger side inlet to the Y-Pipe.
  3. Step 3. Next, slide the Muffler Assembly into the outlet of the Y-Pipe, and fasten the hanger to the rubber, factory, isolators. Loosely tighten a 3.00″ TORCA clamp to hold the muffler in place.
  4. Step 4. Next, install the Over-Axle Pipe. Slide a 3″ TORCA clamp on the muffler outlet and loosely tighten to hold in place. Also attach the hangers to the factory isolators.
  5. Step 5. Install the Helmholtz J-Pipe using a 2.50″ TORCA Clamp, and be sure to cap the end using the provided MF label Cap, also with a 2.50″ TORCA.
  6. Step 6. Lastly, install the tailpipe resonator assembly utilizing a 3.00″ TORCA clamp. From Rear to Front, tighten the entire assembly. Be sure to re-tighten after the first 100 miles after all components have been properly heat cycled.MAGNAFLOW-2023-Sequoia-Overland-FIG- \(10\)
