Parts for your 2005 Honda Stream-Exhaust mount

2005 Honda Stream exhaust mount: what it is and how to look after it

Based on the Honda Stream RN1–RN5 Workshop Manual (2001–2006), the Honda Electronic Parts Catalogue (EPC), and common OEM/aftermarket parts catalogues for the RN-series Stream, the 2005 Honda Stream is fitted with exhaust mounts (rubber hangers). These mounts suspend the exhaust system and isolate vibration, so the part is absolutely relevant to this vehicle.

On the 2005 Stream, the exhaust mounts are small but hard-working rubber isolators that hold the front pipe, mid-section and rear muffler in position. Their main job is to keep the system aligned under the car while soaking up engine and road vibrations. That means less droning in the cabin, fewer knocks over bumps, and the right clearance to the bumper, subframe and heat shields.

As part of routine servicing, it’s smart for owners to have the mounts inspected whenever the car is up on a hoist—typically every service interval. The technician will look for perished rubber, splits, stretched holes and any rust or cracking in the metal hangers welded to the exhaust. Telltale clues that the mounts are on the way out include a tailpipe that sits lower than usual, rattles at idle or when setting off, and clunks over driveway lips or speed humps.

Replacement is straightforward with the right care. Supporting the exhaust with a jack stand, a little silicone spray or soapy water helps slide the old rubbers off the pegs. New mounts go on the same way—no need to over-force them. Many owners choose OEM-grade rubber for the best balance of refinement and durability, polyurethane options can last longer but may pass a touch more vibration into the cabin. If one rear mount has failed, doing the pair together often restores proper alignment and saves a second visit.

There’s no fixed lifespan, but in Australian and New Zealand conditions it’s common to see mounts last 120,000–200,000 km, sooner on vehicles that tow, live near the coast, or see lots of corrugated roads. After fitting, a quick check for clearances to the bumper, heat shields, towbar and suspension arms is worth the extra minute, and the flex joint shouldn’t be left twisted or preloaded.

• Listen for new knocks, buzzes or droning—early signs of tired mounts.
• Inspect during every service, especially after an exhaust repair or impact.
• Replace damaged metal hangers or rusty brackets at the same time.

Popular question: How many exhaust mounts does a 2005 Honda Stream use?

Most 2005 Streams run three to four rubber hangers across the system, with some variants using a fifth. The exact count can vary with engine and exhaust configuration, but expect at least one mid-section mount and two around the rear muffler.

Popular question: What symptoms point to worn exhaust mounts on a 2005 Honda Stream?

Common symptoms include a sagging tailpipe, rattles at idle, clunks over bumps, and vibration that wasn’t there before. Sometimes the exhaust will tap a heat shield or bumper cut-out, leaving shiny rub marks.

Popular question: Is DIY replacement realistic for 2005 Honda Stream exhaust mounts?

Yes, for many owners. With axle stands, basic hand tools and silicone spray, each mount can often be swapped in 30–60 minutes. Let the exhaust cool fully, support it while the mount is off, and inspect the metal pegs and brackets for rust or cracks before refitting.
