Step-by-step guide to installing a side exit catback exhaust on a 2016-2023 Toyota Tacoma. Includes common mistakes and tips for a smooth DIY install.

Quick answer

Installing a side exit catback exhaust on your 2016-2023 Toyota Tacoma is a straightforward DIY job that typically takes 1-2 hours. The REMARK side exit catback system bolts directly to the factory hangers, but careful alignment and torque sequencing are key to avoiding rattles and leaks.

Why choose a side exit catback?

A side exit catback exhaust routes the tailpipe out the side of the truck rather than out the back, giving the Tacoma a cleaner, more aggressive look and freeing up space under the rear bumper for off-road clearance. The REMARK side exit catback is a used part that was test-fit on a Tacoma, so you may notice minor scratches or blemishes—these are cosmetic and do not affect performance.

What to expect from a used system

The REMARK side exit catback is sold as an open-box, used part. It was installed on a vehicle for test fitting and marketing media, so expect some surface wear. All gaskets and hardware are included, and free ground shipping applies to the lower 48 states. Check the condition upon arrival and replace any worn gaskets if needed.

Installation steps

Step 1: Prep and safety: Park on level ground, let the exhaust cool completely, and disconnect the battery negative terminal. Apply penetrating oil to the factory exhaust flange bolts and hanger rubbers 15 minutes before starting. Common mistake: Skipping penetrating oil can snap rusted bolts. Always spray ahead of time.
Step 2: Remove the factory catback: Support the factory exhaust with a jack or stands, then unbolt the flange at the catalytic converter. Pull the hangers free from the rubber isolators and lower the old system. Keep the factory hangers if they are in good condition. Checkpoint: The REMARK system uses the same hanger positions—do not cut or modify the factory hangers.
Step 3: Test fit the new side exit catback: Loosely assemble the REMARK catback sections on the ground, then lift them into position. Start all flange bolts and hanger hooks by hand to ensure alignment before tightening anything. Common mistake: Tightening bolts too early can cause the system to sit crooked. Keep everything loose until all pieces are aligned.
Step 4: Tighten and torque: Tighten the flange bolts in a crisscross pattern to the manufacturer’s torque spec (typically 30-35 ft-lb). Recheck hanger engagement and adjust the tailpipe position so it clears the frame and body panels. Checkpoint: Leave a 1/4-inch gap between the tailpipe and any body panel to prevent rattles when the system heats up.
Step 5: Final check and test: Reconnect the battery, start the engine, and listen for leaks or rattles. Let the system idle for 5 minutes, then rev gently to verify the sound and fit. Re-torque the flange bolts after a heat cycle if needed. Common mistake: Forgetting to re-torque after the first heat cycle can lead to exhaust leaks. Always check again after a short drive.
