Parts for your 2006 Toyota Aurion-Exhaust mount

2006 Toyota Aurion exhaust mount — what it does and how to look after it

Yes, the 2006 Toyota Aurion uses exhaust mounts (also called rubber hangers or exhaust insulators). Technical sources back this up: Toyota’s Electronic Parts Catalogue for the GSV40-series Aurion lists “insulator, exhaust pipe support” at several positions along the system, and the Toyota Repair Manual for GSV40 exhaust removal/installation procedures instructs technicians to unhook the exhaust from rubber supports. General service manuals for the XV40 platform also reference these rubber hangers during muffler and centre pipe work. So an exhaust mount is absolutely relevant on this model.

On the Aurion, the exhaust mounts are small but crucial. They support the weight of the pipes and muffler while isolating vibration from the cabin. Because the exhaust grows with heat and moves with engine torque, the rubber mounts allow controlled movement so the system doesn’t crack, knock on the underbody, or transfer droning straight into the car. Good mounts keep the tailpipe sitting straight, protect welds and flanges, and help prevent stress on the front pipe and manifold connections.

As part of routine servicing, it’s smart to check the mounts every 20,000–30,000 kilometres or whenever the exhaust is being worked on. Look for perished rubber, splits, heavy sagging, or oil-soaked insulators (oil and heat accelerate degradation). If the tailpipe sits low, there’s a thud on start-up/shut-down, or a rattle over bumps, odds are at least one mount is done.

• Inspect on a cool exhaust, ideally on a hoist, make sure there’s clearance to heat shields and the rear bumper.
• Replace any cracked or overly hard mounts, doing them in pairs or across the rear section keeps the system level.
• Use a silicone spray to slide the hangers off and on, don’t lever against thin exhaust brackets.
• Stick with genuine-spec rubber for daily driving, stiffer polyurethane can suit modified systems but may add cabin vibration.
• After refitting, check all clearances and recheck bracket fasteners to the service manual’s torque guidance.

The Aurion typically runs multiple mounts from the centre pipe to the rear muffler. A fresh set brings back proper alignment, stops knocks, and makes the cruiser-like cabin as quiet as it should be.

Popular questions

How many exhaust mounts does a 2006 Toyota Aurion have?

Most stock Aurion GSV40 systems use around four rubber insulators across the centre and rear sections. Variations can occur by trim and market, so a quick look underneath or checking the VIN in the Toyota parts catalogue is the safest way to confirm.

What are the signs an Aurion’s exhaust mount is failing?

Common giveaways are a droopy tailpipe, a thud on start-up or shutdown, rattles over bumps, or the system tapping a heat shield. You might also feel more vibration in the cabin. If a mount has perished or torn, replacement is the fix.

Should owners upgrade to polyurethane mounts?

Poly mounts can control movement better on performance or heavier aftermarket exhausts, but they can pass more vibration into the body. For a daily-driven Aurion on a standard system, quality rubber mounts usually give the best balance of comfort and durability.
