Parts for your 2009 Honda Stream-Exhaust mount

2009 Honda Stream exhaust mount — purpose, care, and when to replace

Yes, the 2009 Honda Stream uses exhaust mounts. Technical references back this up: the Honda Stream RN6–RN9 service manual’s Exhaust System section shows multiple rubber insulators (hangers) supporting the front pipe, centre section, and rear muffler, Honda’s electronic parts catalogue (EPC) lists these rubber mounts and associated brackets for the model, and AU/NZ aftermarket fitment catalogues stock direct‑fit exhaust mounting rubbers specifically for the 2006–2014 Stream. So an exhaust mount is absolutely relevant to this vehicle.

On the Stream, the exhaust mounts are small but crucial. They’re rubber insulators that suspend the exhaust from the underbody, keeping the pipework centred, absorbing vibration, and allowing a bit of movement as the engine shifts under load. Good mounts mean less cabin buzz, no banging over bumps, and correct alignment so flanges and gaskets don’t cop extra stress. When they harden, crack, or stretch, the exhaust can sit off‑centre, rattle against heat shields, or thump the subframe, and that can quickly snowball into broken hangers, split welds, or a leaking joint.

Common signs it’s time to replace the exhaust mounts on a 2009 Honda Stream include:

• Rattles or dull thumps from the rear or mid‑section, especially on start‑up, over speed humps, or when cornering
• Exhaust tip sitting crooked in the bumper cut‑out or noticeably lower than usual
• Visible cracks, glazing, or elongation in the rubber insulators
• Excessive exhaust movement when gently rocked by hand (with the car safely raised and cooled)

During regular servicing, it’s smart to give the mounts a quick once‑over. On older vehicles doing Aussie or Kiwi kilometres, rubber fatigue is common. Replacement is straightforward: safely support the car, let the exhaust cool, spray the mount pegs with penetrant, then lever off the old rubbers and push on new quality insulators. Replacing mounts in pairs or across the section (e.g., rear muffler mounts together) helps keep alignment sweet. If a mount keeps failing, check for a tired engine mount or a bent bracket throwing the exhaust out of line.

For extra longevity, confirm there’s a small, even air gap around heat shields and the subframe, and that the system isn’t pre‑loaded when tightened. Use a dab of silicone‑safe lubricant to install new rubbers, avoid excessive prying, and always follow current Honda service information for jacking points and any torque specs on related brackets. Done right, new mounts will keep the Stream’s exhaust quiet, centred, and drama‑free.

Popular questions about 2009 Honda Stream exhaust mounts

How often should exhaust mounts be replaced on a 2009 Honda Stream?
There’s no fixed interval, as it depends on heat cycles, road conditions, and age. Many owners find the originals last years, but by the time the car is well into its second decade, the rubbers are often perished. Check them at each service and replace at the first sign of cracking, sag, or noise.

Can you drive with a broken exhaust mount?
You can sometimes limp home, but it’s not ideal. A failed mount lets the exhaust swing, which can bang on the body, stress flanges, and damage oxygen sensor wiring. If it’s hanging low or hitting the underbody, get it sorted promptly.

Do aftermarket exhausts need different mounts on the Stream?
Many cat‑back systems reuse the factory‑style rubbers, but heavier or larger systems may benefit from upgraded, stiffer insulators. Always check the exhaust supplier’s fitment notes and ensure there’s proper clearance around the bumper and heat shields.
