2006 Toyota Vitz/Yaris Exhaust Mount

Exhaust mounts are absolutely used on the 2006 Toyota Vitz/Yaris (XP90 series). Toyota’s factory Repair Manual for the XP90 platform details the exhaust system being suspended from the body with rubber insulators/hangers, and the Toyota Electronic Parts Catalog (EPC) for NCP90/NCP91 lists multiple exhaust pipe hanger insulators for this model. Independent guides such as the Haynes Toyota Yaris 2005–2010 manual also note the exhaust is carried on rubber mounts to isolate vibration. So, an exhaust-mount is relevant and fitted on the 2006 Vitz/Yaris.

On this model, the exhaust mounts (often called rubber hangers or insulators) keep the exhaust properly supported while soaking up vibration and road shock. They let the pipe and muffler move a touch as the engine twists and the system heats up, stopping metal-on-metal contact, rattles, and premature cracks in welds. Typically there are several mounts along the system—commonly one forward, one mid, and one or two near the rear muffler—to keep the pipe aligned and clear of the body, heat shields, suspension and bumper.

There isn’t a strict replacement interval, they’re a service item to inspect routinely. A good rule is to check them at every service or at least every 10,000–15,000 km, as well as during NZ WOF or AU roadworthy checks where a secure, leak-free exhaust is required. Tell-tale signs they’re past their best include a sagging tailpipe, thumps over bumps, knocking on start-up, visible cracking in the rubber, or a melted or deformed mount near the rear box. If the exhaust sits skew-whiff in the bumper cut-out, that’s another giveaway.

• When replacing, support the exhaust on a stand, spritz the old mounts with silicone spray, and lever them off the pegs.
• Swap like-for-like mounts, OE-style rubber gives the best NVH on a stock Yaris, while polyurethane is firmer but can add a touch of cabin buzz.
• Refit so the system has even clearance all round and doesn’t preload the pipe, recheck after a short drive once it’s heat-cycled.

A small outlay on fresh mounts can save the muffler and flex joint from strain, keep drone at bay, and stop annoying knocks against the underbody—exactly what owners expect from a tidy 2006 Vitz/Yaris.

How many exhaust mounts does a 2006 Vitz/Yaris have?

Most XP90 Yaris/Vitz cars use three to four rubber hangers: typically one near the front pipe, one mid-mounted, and one or two supporting the rear muffler. Variations can occur with different body styles or market-specific exhaust layouts.

It’s best to visually confirm on the hoist, as some cars may have had exhaust sections replaced that alter the hanger count or positions.

What are the signs the mounts need replacing?

Common symptoms include a droopy tailpipe, rattles or knocking over bumps, thuds on start-up or shutdown, and visible cracks or splits in the rubber. If the exhaust touches heat shields or the bumper, the mounts may be stretched or perished.

Any contact points or fresh soot marks around the system are a prompt to replace the mounts and re-align the pipework.

Can polyurethane hangers be used on a stock Yaris?

Yes, firmer polyurethane hangers can hold the system tighter and reduce movement, which some owners prefer. However, they can transmit a bit more vibration into the cabin on a daily-driver Vitz/Yaris.

For factory-like comfort and noise control, OE-style rubber is usually the pick. Poly suits cars with sportier exhausts or where clearance is tight.
