2006 Honda Stream Exhaust Mounts — What They Do and When to Replace Them

Technical sources confirm the 2006 Honda Stream is fitted with exhaust mounts (also called exhaust hangers). Honda’s official service literature for the RN6/RN7 Stream covers removal and installation of “muffler hangers,” and the Honda Electronic Parts Catalogue lists multiple rubber hanger insulators and brackets along the front pipe, centre section and rear muffler. Independent workshop manuals and OE-style parts diagrams for the 2006 Stream likewise depict these mounts supporting and isolating the exhaust system.

On this model, the exhaust mounts are small but vital rubber insulators that suspend the exhaust from the underbody. They keep weight off the manifold and catalytic converter, control movement over bumps, and soak up vibration so the cabin isn’t buzzing. They also help the tailpipe sit straight so it doesn’t knock the subframe or melt the bumper.

For a 2006 Honda Stream that’s doing daily duty around Aus or NZ, routine checks are simple and worthwhile. Rubber hardens and perishes with age, and coastal climates plus road grime can hasten cracking. During a service or whenever the car’s on a hoist, a quick look at the hangers can prevent annoying rattles and premature stress on joints and flanges.

• Signs the exhaust mounts need attention:
  • Rattling, thudding or droning from the rear, especially over bumps or at idle.
  • Tailpipe sitting off-centre or touching the bumper/heat shield.
  • Visible cracks, splits, elongation, or oily, swollen rubber.
  • Excessive movement when the exhaust is pushed by hand.

• Service and replacement tips:
  • Inspect mounts at each service or at least every 20,000–30,000 kilometres.
  • Replace any perished or stretched hangers in pairs around the affected section for even support.
  • Use silicone spray to slip old rubbers off the pegs, avoid levering on thin brackets.
  • Check adjoining brackets and heat shields for corrosion and tightness after fitting new hangers.
  • Polyurethane hangers can reduce movement but may transmit more vibration, quality rubber suits most daily drivers.
  • If the system has been knocked or grounded, inspect all mounts before re-aligning the exhaust.

There’s no special maintenance beyond inspection and timely replacement, but it pays to act early. Fresh mounts keep the Stream quiet, protect welds and gaskets, and help the rear muffler sit exactly where Honda intended.

Popular questions about 2006 Honda Stream exhaust mounts

How many exhaust mounts does a 2006 Honda Stream have?
Most 2006 Streams have several mounts spread along the system—commonly one near the front/centre and two around the rear muffler. Exact count can vary with trim and market options, but expect three to five hangers in total.

This spacing keeps the pipe supported without stressing joints. When replacing, match the style and location to what’s on the vehicle.

Can worn exhaust mounts cause vibration or knocking?
Yes. Perished rubbers let the exhaust swing and touch heat shields, the subframe, or the bumper, creating knocks over bumps and a droning note at certain revs.

Restoring firm, correctly sized hangers usually brings the exhaust back to its designed height and quietens the cabin.

Are polyurethane mounts a good upgrade?
They can be, depending on priorities. Poly mounts better control movement and can last longer, which is handy if the car carries loads or sees rough roads.

For a comfy, quiet daily Stream, OE-style rubber is typically the best balance. Go poly if a firmer feel and extra durability outweigh a slight increase in vibration.
