Step-by-Step Installation Guide

Step 1: Unpack Your Magnaflow Exhaust System

Your Magnaflow exhaust package includes three main components:

  1. Resonator
  2. Center pipe
  3. Muffler section

The front resonator comes with a mounting flange that bolts directly onto your stock catalytic converter. The center pipe is secured with the supplied exhaust clamps, and the rear muffler section exits the car through the center of the rear bumper.

Step 2: Remove the Factory Skid Plate/Heat Shield

Using a socket wrench, remove the factory skid plate/heat shield from the chassis. Keep this piece safe as you will need to reinstall it later.

Step 3: Detach the Mid Exhaust Mounting Bracket

Follow the factory exhaust towards the catalytic converter and remove the mid exhaust mounting bracket from the chassis using a socket wrench. Slip the exhaust hangers out of the rubber mounting bushings and set this piece aside for reuse.

Step 4: Remove the Factory Exhaust System

Locate the flange on the catalytic converter, which has two bolts that need to be removed. Be cautious during this step as the entire exhaust system is only supported by two rear hangers on the muffler. Have your friend hold up the front section to prevent it from crashing to the ground.

Step 5: Free the Factory Exhaust

Go to the back of the car and remove the hangers from the rubber bushings to free the factory exhaust. Congratulations, you have successfully removed the factory exhaust system.

Step 6: Install the Magnaflow Exhaust System

Install the Magnaflow system in the reverse order of removal:

  1. Match the resonator section with the flange on the catalytic converter and bolt them together.
  2. Slip the connecting pipe into the resonator pipe and secure it with the supplied clamp.
  3. Attach the connecting pipe to the factory chassis mount and secure the hangers into the rubber bushings.

Step 7: Connect the Muffler Section

Connect the muffler section to the connecting pipe. Slip the exhaust hangers on the muffler into the hanging rubber bushings first, then fit the rear section into the connecting pipe. Tighten the supplied clamp and ensure all connections are secure. Reinstall the skid plate/heat shield.

Step 8: Final Checks

Start the car and check for any exhaust leaks. If everything is secure, enjoy your Mini Cooper S's new throaty growl and performance boost.
