Once the Flowmaster exhaust is in place, secure all clamps and hangers. Double-check that everything is aligned properly and that there are no kinks in the pipes. Tighten all bolts to the manufacturer’s specifications to prevent any leaks.
Step 5: Test the Installation
Before lowering the vehicle, start the engine to check for any exhaust leaks. Listen for any unusual sounds that may indicate a loose connection. If everything sounds good, lower the vehicle back to the ground.
