Parts for your 2019 Honda Odyssey-Exhaust mount

2019 Honda Odyssey exhaust mount — what it does and how to look after it

Technical sources including the 2019 Honda Odyssey (RL6) Service Manual’s Exhaust System section, Honda Genuine Parts catalogues listing “insulator, exhaust” and “muffler hanger,” and mainstream aftermarket fitment guides from brands like Walker and Bosal confirm the 2019 Odyssey is fitted with multiple exhaust mounts (rubber hangers and steel brackets). So, an exhaust-mount absolutely applies to this vehicle.

On the Odyssey, the exhaust mounts are the quiet achievers that hold the exhaust system in place while letting it move a little as the engine torques and the pipes heat up. The rubber insulators isolate vibration so the cabin stays calm, and they keep the muffler and pipes correctly aligned so nothing knocks on the underbody. Without good mounts, owners can cop rattles, thumps over bumps, and extra stress on joints, flanges and the flex section.

This model typically uses several mounts from the centre pipe back to the rear muffler, with at least two at the muffler and others supporting the mid‑section. They’re made from heat‑resistant rubber, but years of heat cycling, road grime and the odd scrape can cause cracking, perishing or stretching. When that happens, the exhaust can sag or shift, and clearances to the bumper, subframe or suspension can disappear.

As part of routine servicing, it’s smart to eyeball the Odyssey’s exhaust mounts every 20,000–30,000 kilometres or any time the vehicle is on a hoist for brakes, tyres or oil. Signs a mount is on the way out include:

• Exhaust tapping or thunking on start‑up, over speed humps, or on rough roads
• Visible cracking, tearing or a glossy “perished” look to the rubber
• Sagging tailpipe or a muffler that sits off‑centre in the bumper cut‑out
• New exhaust leaks soon after other exhaust work (a stressed joint from poor support)

Replacement is straightforward for a trained tech. Let the exhaust cool, support it with a stand, then swap the insulators one by one so alignment stays true. A spritz of silicone spray helps the new rubbers slide on, and any rusty steel hangers or brackets should be replaced at the same time. After fitment, check clearances around the subframe, heat shields and bumper, and make sure the system sits naturally without preload. For most Odysseys, budget around half an hour per mount, more if hardware is corroded.

Keeping fresh, correctly sized mounts under the Odyssey protects the catalytic converters and flex joint, keeps noise levels legal, and stops annoying cabin buzz—small parts doing a big job for long‑term reliability.

Popular questions

How many exhaust mounts does a 2019 Honda Odyssey have?
Most 2019 Odysseys run several mounts from the centre pipe to the rear muffler—commonly four to six in total. Expect at least two at the rear muffler and others along the mid‑pipe. Exact count can vary with market equipment and any tow or accessory packages.

What are the signs the Odyssey’s exhaust mounts need replacing?
Tell‑tales include a tailpipe that sits crooked, knocking noises over bumps or at start‑up, visible cracks or tears in the rubber, and fresh exhaust leaks after recent work. If the exhaust touches the body or bumper, the mounts are likely stretched or perished.

Is it safe to drive if an exhaust mount is broken?
It’ll usually still drive, but it’s not a great idea. A loose exhaust can whack the underbody, strain joints and the flex section, and may get noisy enough to breach local regulations. Replacing the failed mount promptly helps avoid bigger repair bills.
