Tools and Materials Needed
- MagnaFlow Cat-Back Exhaust Kit
- Socket Set
- Wrench Set
- Jack and Jack Stands
- Safety Glasses
- Gloves
- Torque Wrench
- Lubricant Spray
Preparation
Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Gather all tools and materials listed above. Wear safety glasses and gloves to protect yourself during the installation process.
Step 1: Lift the Vehicle
Using a jack, lift the rear of your Grand Cherokee SRT and secure it with jack stands. This will provide you with the necessary clearance to work underneath the vehicle.
Step 2: Remove the Stock Exhaust System
Start by locating the stock exhaust system. Use a socket set to remove the bolts securing the exhaust to the exhaust manifold and the rubber hangers holding it in place. It may help to spray lubricant on the bolts to make removal easier.
Carefully lower the stock exhaust system and set it aside. Make sure to keep all the hardware for the new exhaust installation.
Step 3: Install the MagnaFlow Cat-Back Exhaust
Begin by positioning the MagnaFlow cat-back exhaust system under the vehicle. Align the exhaust pipes with the mounting points and hangers. Ensure that the exhaust tip is positioned correctly for optimal appearance and clearance.
Start attaching the exhaust by securing the inlet pipe to the exhaust manifold using the hardware provided in the kit. Tighten the bolts securely but do not overtighten.
Step 4: Secure the Exhaust System
Once the inlet pipe is secured, continue to attach the remaining sections of the exhaust system. Make sure to install all rubber hangers and clamps included in the MagnaFlow kit. Adjust the positioning of the exhaust as needed to ensure a proper fit.
Step 5: Tighten All Connections
Using a torque wrench, tighten all bolts to the manufacturer’s specifications. This will ensure that the exhaust system is securely fastened and will not come loose during operation.
Step 6: Lower the Vehicle
Once all connections are tightened, carefully lower the vehicle back to the ground using the jack. Remove the jack stands and ensure everything is clear before starting the engine.
Step 7: Test the Exhaust System
Start your Grand Cherokee SRT and listen for any unusual noises. Check for leaks around the connections. If everything sounds and looks good, take the vehicle for a short test drive to ensure the exhaust system is functioning properly.
Conclusion
Installing a MagnaFlow cat-back exhaust on your Grand Cherokee SRT is a straightforward process that can yield significant performance improvements. With proper tools and careful installation, you can enjoy the benefits of enhanced horsepower and a more aggressive exhaust note.
