Understanding the MBRP Exhaust System

Before diving into the installation, it’s important to understand what sets an MBRP exhaust system apart from stock or other aftermarket options. MBRP exhausts are typically constructed from high-grade aluminized steel or stainless steel, offering superior resistance to rust and heat. Their design focuses on improving exhaust gas flow by reducing restrictions, which can lead to better throttle response, increased torque, and improved fuel efficiency. Additionally, the signature sound produced by MBRP systems is a major appeal for many drivers, combining a throaty growl with a refined tone that can be adjusted depending on the specific model and vehicle application.

Preparation Before Installation

Preparation is a critical phase that sets the foundation for a smooth and safe installation process. Follow these steps to ensure you are ready:

  • Gather the necessary tools: A complete socket set, wrenches, penetrating oil (like WD-40), jack stands or ramps, safety gloves, eye protection, and possibly a torque wrench are essential. Depending on your vehicle, you might also need a hacksaw or exhaust pipe cutter if the old system is welded or rusted in place.
  • Work in a safe environment: Choose a flat, stable surface such as a garage floor or driveway. If working outdoors, ensure the area is well-lit and free from distractions.
  • Cool down the engine: Never attempt to remove or install exhaust components while the engine is hot. Exhaust parts can reach extremely high temperatures and cause serious burns.
  • Review the manufacturer’s instructions: MBRP includes detailed instructions tailored to specific vehicle makes and models. Familiarize yourself with the components, hardware, and sequence of assembly to avoid mistakes.
  • Inspect the new parts: Lay out all components and verify that nothing is missing or damaged during shipping. This includes pipes, clamps, hangers, gaskets, and hardware.
  • Assess the condition of your vehicle’s undercarriage: Check for rust or damage in the exhaust mounting areas. Address any issues beforehand to ensure proper fitment and longevity of the new system.

Removing the Old Exhaust System

Removing the existing exhaust system can be challenging, especially on older vehicles where rust and corrosion may have seized bolts and clamps. Follow this step-by-step procedure:

  • Raise the vehicle securely: Use a jack to lift the vehicle and place it firmly on jack stands or drive it onto ramps. Never rely solely on a hydraulic jack for support while working underneath.
  • Spray penetrating oil: Apply penetrating oil on all bolts, nuts, and clamps that secure the exhaust components. Allow it to soak for 10-15 minutes to help loosen rusted fasteners.
  • Locate exhaust mounting points: Identify the flange connections, clamps, and rubber hangers holding the exhaust in place. Most systems have bolts at the manifold or catalytic converter flange, mid-pipes, mufflers, and tailpipes.
  • Loosen and remove fasteners: Using your socket set or wrench, carefully loosen and remove all bolts and clamps. If a bolt is seized, applying heat with a propane torch (safely) or using a breaker bar can help. As a last resort, cutting the pipe may be necessary.
  • Detach rubber hangers: Use a pry bar or exhaust hanger removal tool to free the exhaust from its rubber isolators. Be cautious to avoid damaging the hangers, as you may reuse them with the new system.
  • Remove the old exhaust system: Once all fasteners and hangers are free, carefully lower and remove the old system from under the vehicle. It may require some maneuvering to clear suspension components or the driveshaft.
  • Inspect connection points: Clean the flanges, mounting brackets, and hangers to prepare for the new installation. Repair or replace any damaged hangers or mounting points.

Installing the MBRP Exhaust System

With the old exhaust removed, you’re ready to install the MBRP system. The installation requires patience and attention to detail to ensure a proper fit and leak-free operation.

Step 1: Dry Fit Components

Before fully tightening any clamps or bolts, loosely assemble the exhaust system by fitting all components together. Start from the front of the vehicle at the exhaust manifold or catalytic converter flange and work your way back to the tailpipe. This process allows you to check alignment, clearances, and hanger locations.

Step 2: Secure Flange Connections

Attach the front pipe or header pipe to the vehicle’s exhaust manifold using the original or supplied gaskets. Tighten the flange bolts evenly but leave them slightly loose to allow for adjustment during final alignment.

Step 3: Attach Mid-Pipes and Muffler

Connect the intermediate pipes and muffler sections. Use the provided clamps to secure joints, but avoid fully tightening them until the entire system is positioned correctly. Ensure the muffler is oriented as per the instructions, as incorrect orientation can affect sound and clearance.

Step 4: Install Tailpipe and Tips

Fit the tailpipe into place, aligning it with the rear bumper and exhaust exit points. MBRP systems often include polished or black-coated exhaust tips that enhance visual appeal. Adjust the tip position to your preference before tightening clamps.

Step 5: Attach to Exhaust Hangers

Reconnect the exhaust to the factory rubber hangers or install new hangers supplied with the MBRP kit. Proper hanger placement prevents excessive movement, reduces stress on joints, and minimizes noise and vibration.

Step 6: Final Alignment and Tightening

Check the entire exhaust system for clearance from the vehicle’s body, suspension components, fuel lines, and brake lines. Adjustments may be necessary to prevent rattling or contact that could lead to damage. Once satisfied with the positioning, systematically tighten all clamps and flange bolts to the manufacturer’s recommended torque specifications. Using a torque wrench ensures a secure fit without over-tightening, which can strip threads or deform flanges.

Final Checks and Testing

After installation, performing thorough checks and tests is essential to confirm the system’s integrity and performance.

  • Visual inspection: Verify that all clamps, bolts, and hangers are properly secured and that the exhaust system is stable with no excessive movement.
  • Leak check: Start the engine and listen carefully for any exhaust leaks, which typically sound like hissing or popping near joints. Use your hand (carefully and at a safe distance) to feel for escaping gases around connections.
  • Heat clearance check: After running the engine for a few minutes, inspect the exhaust’s clearance from heat-sensitive components like brake lines and fuel tanks to avoid potential hazards.
  • Road test: Take the vehicle for a short drive, listening for unusual noises such as rattles, clanks, or excessive drone. Ensure throttle response feels improved and that there are no warning lights on the dashboard.
  • Re-tighten if necessary: After the initial drive, allow the exhaust to cool, then recheck all fasteners and clamps. Vibrations from driving can sometimes loosen hardware, so a follow-up tightening is recommended.

Additional Tips for a Successful Installation

  • Wear appropriate safety gear: Gloves protect your hands from sharp edges and hot surfaces, while safety glasses guard against debris when working underneath the vehicle.
  • Work with an assistant: Some components can be heavy or awkward to maneuver alone. Having a helping hand can make the process safer and more efficient.
  • Use anti-seize compound: Apply anti-seize lubricant to bolts and threads during installation to prevent future rusting and ease removal if needed.
  • Consider exhaust wrap or heat shields: For vehicles with sensitive components near the exhaust, adding heat wraps or shields can reduce under-hood temperatures and protect wiring or hoses.
  • Keep the old exhaust system: Store the removed exhaust in case you wish to revert to stock or sell the aftermarket system in the future.
  • Consult professionals if unsure: If you encounter difficulties, corrosion issues, or welding requirements beyond your skillset, seeking help from an experienced exhaust technician is advisable to avoid damage or safety risks.
