This procedure covers the replacement or installation of an aftermarket exhaust tip on a 2014-2019 Toyota Corolla with 1.8L I4 engine.

Warnings

Tools required

Parts

• Exhaust tip × 1 — Use OEM specification or aftermarket equivalent
• Exhaust clamp (if clamp-on style) × 1 — Match pipe diameter

Preparation

1. Park vehicle on level ground and ensure the engine and exhaust system are completely cool to the touch
2. If additional clearance is needed, safely raise and support the rear of the vehicle on jack stands
3. Inspect the existing exhaust pipe outlet to determine if it is the factory tip or a previous aftermarket installation
4. Determine tip installation method: slip-on with clamp, bolt-on, or weld-on

Procedure

1. 1

   Access exhaust tip area
   Locate the exhaust outlet at the rear passenger side of the vehicle beneath the rear bumper. Visually inspect the current tip and mounting method. If working from the ground is difficult, raise the vehicle for better access.
2. 2

   Remove existing exhaust tip (if applicable)
   If replacing an aftermarket tip, loosen and remove any clamps using a socket wrench. For factory exhaust outlet, note that the pipe may be a single piece with the muffler. Apply penetrating oil to any rusted fasteners and allow 5-10 minutes to soak. Slide off any slip-on tips by twisting and pulling rearward.
3. 3

   Clean exhaust pipe outlet
   Use a wire brush to clean the outer surface of the exhaust pipe where the new tip will attach. Remove rust, carbon buildup, and debris to ensure proper fit and seal. Verify the pipe diameter matches the new exhaust tip specifications.
4. 4

   Test fit new exhaust tip
   Slide the new exhaust tip onto the exhaust pipe outlet without tightening any fasteners. Ensure the tip sits flush and is properly aligned with the bumper cutout. The tip should be straight and positioned aesthetically. Mark the desired depth and rotational orientation.
5. 5

   Install exhaust tip clamp
   Remove the tip and position the exhaust clamp around the pipe where it will secure the tip. Slide the new tip back onto the pipe to the marked position, ensuring it extends appropriately beyond the bumper. Position the clamp over the tip's clamping area.
6. 6

   Secure exhaust tip
   Tighten the clamp bolts gradually in a cross pattern to ensure even pressure. Do not overtighten as this may crush the pipe or tip. Tighten until the tip is firmly secured and cannot rotate or slide. Verify alignment one final time before fully tightening.
7. 7

   Final inspection
   Visually inspect the installed tip to ensure it is straight, properly positioned relative to the bumper, and securely fastened. Check for adequate clearance from the bumper and underbody components. Gently attempt to rotate or move the tip to confirm secure installation.

Reassembly

1. Lower vehicle if it was raised on jack stands
2. No additional reassembly required for this procedure

Verification

• Start the engine and listen for exhaust leaks at the tip connection point
• Verify no rattling or vibration from the exhaust tip during idle and light acceleration
• Perform a visual inspection from the rear of the vehicle to confirm proper alignment and positioning
• Check that the tip does not contact the bumper or body panels during engine vibration
