Parts for your 2010 Honda Stream-Exhaust mount

2010 Honda Stream exhaust-mount — what it does and how to look after it

Based on Honda’s own service literature for the RN6–RN9 series and the Honda electronic parts catalogue for the 2010 Honda Stream, the exhaust system is suspended by multiple rubber exhaust mounts (also called hangers or insulators). These mounts are therefore absolutely relevant and fitted to the 2010 Honda Stream, supporting the mid‑pipe and rear muffler and isolating vibration from the cabin.

On a 2010 Honda Stream, the exhaust-mounts are the quiet heroes. They cradle the exhaust so it sits at the right height and angle, soak up engine movement, and stop the muffler banging over bumps. Because they’re rubber, they also cut down on vibration and that droning hum that can creep into the cabin on the motorway. Over time, heat, road grime, and good old Kiwi/Aussie weather make the rubber harden, crack, or stretch, which lets the system sag or rattle.

As part of routine servicing, it’s smart to eyeball the mounts every service or roughly every 10,000–15,000 kilometres. Look for perished rubber, visible cracking, elongated holes, or shiny scrape marks around the tailpipe that hint the system is touching the body. If one mount’s on the way out, the rest won’t be far behind, so replacing them as a set around the affected section is good practice and still very cost‑effective.

Replacement is straightforward for a home mechanic: let the exhaust cool fully, support it with a jack and stands, and spritz the mount rods with silicone spray to slide the old rubbers off. Avoid petroleum-based lubes that can attack rubber. While you’re there, check the steel hanger rods for rust and the exhaust alignment relative to the bumper cut‑out. Refit new mounts in the same orientation (some have an “up” side) and confirm there’s clearance to heat shields and suspension arms through the full range of movement.

Telltale signs it’s time to act include:

• Clunks or thuds from the rear over bumps
• Vibration at idle that wasn’t there before
• A sagging or crooked tailpipe
• Fresh knocks on heat shields or underbody

Don’t ignore it—failed mounts can stress the flex pipe and joints, risk exhaust leaks, and can cop a fail at a WOF or roadworthy if the system’s not securely mounted. Quality aftermarket or genuine Honda rubbers both do the job, choose heat‑resistant items designed for the Stream and you’ll be sweet for years.

Popular questions

How many exhaust mounts does a 2010 Honda Stream have?

Most 2010 Streams (RN6–RN9) use several rubber hangers: typically one around the centre pipe area and two or more at the rear muffler. The exact count can vary slightly by trim and market, but expect three to four mounts in total.

How often should the exhaust mounts be replaced?

There’s no fixed interval. Inspect them at every service, many last 5–10 years, but high heat, short trips, towing, or rough roads can shorten their life. Replace at the first signs of cracking, sagging, or rattles.

Can a DIYer replace the mounts at home?

Yes. With the car safely supported, silicone spray and basic hand tools usually do it. Make sure the exhaust is stone cold, support it while removing the old rubbers, and double‑check alignment and clearances after fitting the new ones.
