Step 2: Loosen left and right stock muffler ball joint clamps.
Step 3: Remove the left and right muffler rubber hanger mount brackets off the chassis and remove stock mufflers.
Step 4: Slide the rubber hanger mounts off the stock mufflers and install onto the aFe Axle Back Mufflers.
Step 5: Using (x1) supplied aFe ball joint clamp, install the left aFe muffler onto the stock mid pipe and back onto the chassis using the original bolts removed from step 3 and tighten. Do not tighten the ball joint clamp.

Note: It is normal for your exhaust system to emit smoke for the first few minutes upon initial start-up due to grease used in the mandrel bending process.
