This procedure covers the removal and installation of the exhaust tip on a 2016-2021 Honda Civic 1.5L Turbo, including proper alignment and securing methods.

Warnings

Tools required

Parts

• Exhaust tip × 1 — Use OEM specification or aftermarket equivalent
• Clamp bolts/nuts (if corroded) × 1 — Use OEM specification

Preparation

1. Ensure vehicle has been off for at least 2 hours to allow exhaust system to cool completely
2. Park vehicle on level ground and engage parking brake
3. If additional clearance is needed, raise rear of vehicle using jack and support with jack stands rated for vehicle weight
4. Spray clamp bolts/nuts with penetrating oil and allow to soak for 10-15 minutes if exhaust is original or shows corrosion

Procedure

1. 1

   Access exhaust tip
   Position yourself under the rear of the vehicle with clear access to the exhaust tip. Identify the connection point where the exhaust tip attaches to the main exhaust pipe. Most 2016-2021 Civic 1.5L Turbo models use a slip-fit connection with a band clamp or bolted flange connection.
2. 2

   Remove clamp or fasteners
   If equipped with a band clamp: Locate the clamp bolt (typically 12mm) and loosen completely, but do not remove entirely. The clamp should open enough to slide off. If equipped with a bolted connection: Remove the fastening bolts using appropriate socket. Clean threads with wire brush if corrosion is present.
3. 3

   Remove exhaust tip
   Slide the exhaust tip rearward off the exhaust pipe. If tip is stuck due to carbon buildup or corrosion, gently twist while pulling to break the seal. Avoid using excessive force that could damage the main exhaust pipe. If severely stuck, apply additional penetrating oil and wait, or carefully use heat if safe to do so.
4. 4

   Clean mating surfaces
   Use wire brush to clean the outer diameter of the exhaust pipe where the tip connects. Remove all carbon deposits, rust, and old gasket material if present. The pipe surface should be smooth and clean to ensure proper seal and fit of the new exhaust tip.
5. 5

   Install new exhaust tip
   Slide the new exhaust tip onto the exhaust pipe, ensuring it is fully seated and oriented correctly (angled cuts should face downward or as designed). The tip should slide on smoothly over the clean pipe. Position the tip to desired depth and angle before tightening, ensuring proper ground clearance and alignment with bumper cutout.
6. 6

   Secure exhaust tip
   If using band clamp: Position clamp over the connection point and hand-tighten the bolt. Ensure clamp is centered on the connection. Gradually tighten the clamp bolt in a star pattern if multiple bolts exist, or evenly if single bolt, until snug. Do not overtighten band clamps as this can damage the exhaust tip. If using bolted flange connection: Apply anti-seize to bolt threads and torque to specification.
7. 7

   Verify alignment and clearance
   Check that exhaust tip is properly aligned with bumper cutout and has adequate clearance from all surrounding components (minimum 10mm clearance recommended). Tip should not contact bumper, suspension components, or body panels. Adjust position as needed before final tightening.
8. 8

   Final tightening
   Perform final tightening of all clamp or fastener hardware. For band clamps, tighten firmly but do not exceed manufacturer specifications (typically 40-50 Nm for stainless band clamps, but verify marking on clamp). Ensure connection is secure and tip does not rotate or slide with hand pressure.

Reassembly

1. Lower vehicle if raised on jack stands
2. Double-check that exhaust tip is secure and properly aligned before starting vehicle

Verification

• Start engine and allow to idle. Listen for any exhaust leaks at the connection point (hissing or ticking sounds indicate leak)
• Visually inspect connection while engine is running for any visible exhaust gases escaping
• Rev engine gently to 2000-3000 RPM and verify no leaks occur under increased exhaust flow
• After test drive, re-inspect exhaust tip alignment and verify it has not shifted position
• Check that exhaust tip remains secure with no excessive movement when pushed by hand (engine off and cool)
