Parts for your 2011 Honda Stream-Exhaust mount

2011 Honda Stream exhaust-mount: what it does and when to replace it

Technical sources confirm the 2011 Honda Stream uses exhaust mounts (also called exhaust hanger rubbers/insulators). The Honda Stream (RN6–RN9) workshop manual’s Exhaust System procedures specify removing and refitting “hanger rubbers” for the centre and rear mufflers, and the Honda Electronic Parts Catalogue for RN6/RN9 lists multiple exhaust hanger rubbers and brackets for the exhaust assembly. These factory references make it clear that exhaust mounts are fitted and required on this model.

The 2011 Honda Stream relies on a set of rubber exhaust mounts to hold the exhaust system in place while isolating noise and vibration. They’re small, inexpensive bits of rubber, but they do a big job—keeping the muffler and pipes sitting at the right height, stopping drumming through the cabin, and protecting the manifold and flex joint from stress when the car hits bumps or twists over driveways.

Over time, those rubbers harden, crack, or stretch from heat, road grime, and Kiwi/Aussie conditions (think coastal air and long highway runs). When they start to give up, the exhaust can sag, rattle over speed humps, or thump against the subframe. Left too long, a droopy exhaust can stress welds and flanges, or rub a hole in the pipe—none of which is kind to the wallet.

As part of routine servicing on a 2011 Honda Stream, a quick inspection of all exhaust mounts is smart. They’re easy to spot near the centre resonator and rear muffler: look for perished rubber, splits, elongated holes, or shiny witness marks where the system has been touching the body. A light pry with a trim tool will reveal excessive softness or cracking. If one is gone, replace them as a set in that section to keep the system level.

Replacement is straightforward: support the exhaust, spritz the hangers with silicone spray, and slide the old rubbers off their pegs. Pop new quality OEM-equivalent hangers on, check clearances to heat shields, bumper, and suspension arms, and make sure the tailpipe sits square. Most shops will have this buttoned up in under an hour. For longevity, consider hangers with heat-resistant compounds if the car tows or sees a lot of hot running.

A good rule of thumb is to inspect at every service and expect replacement somewhere between 80,000–150,000 km depending on climate and use. Staying ahead of tired exhaust mounts keeps the Stream quiet, tidy, and free of avoidable exhaust repairs.

• Common symptoms: rattles over bumps, exhaust sag, thuds on start-up/shut-down, or a droning note at certain revs.
• Good practice: replace stretched or cracked mounts in pairs, check brackets and clamps, and verify heat shield clearances.

FAQs

How often should exhaust mounts be replaced on a 2011 Honda Stream?
There’s no fixed interval, but many owners see wear between 80,000 and 150,000 km. Inspect at every service or WOF/rego check. Heat, towing, and rough roads can shorten their life.

What are the signs the exhaust mounts are failing?
Look and listen for a sagging muffler, rattles over bumps, a thump at start-up, or the tailpipe sitting off-centre. Perished or cracked rubber around the hanger holes is a giveaway.

Can universal exhaust hangers be used on a Honda Stream?
Yes, quality universal hangers can work if the size and stiffness are right. However, OEM-spec parts usually fit best and keep the exhaust sitting exactly where Honda intended.
