Parts for your 2020 Toyota C-hr-Exhaust mount

2020 Toyota C‑HR Exhaust Mount

Exhaust mounts are absolutely used on the 2020 Toyota C‑HR. Toyota’s Service Information (TIS) Repair Manual for the C‑HR (Exhaust Pipe section) details the “exhaust pipe support rubber/insulator” at multiple points along the system, and the Toyota Electronic Parts Catalogue (EPC) for 2020 C‑HR variants (including NGX10/ZYX10 series) lists these rubber hangers by location around the front pipe, centre section and rear muffler. These references confirm the vehicle relies on rubber exhaust mounts to suspend and isolate the exhaust assembly.

On this C‑HR, the exhaust mount’s job is to hold the exhaust securely while letting it move slightly as the engine rocks and the pipework heats and cools. The rubber insulators soak up vibration so there’s no harsh buzzing in the cabin, and they keep the muffler and pipework neatly centred so nothing knocks on crossmembers, heat shields or the rear bumper. They’re simple parts, but they make a big difference to noise, comfort and the longevity of the exhaust.

As part of regular servicing, it’s smart to have the exhaust mounts checked from nose to tail. Rubber can harden, crack or stretch with age, especially with heat cycles and road grime. A quick visual inspection on a hoist will spot perishing or tears, and a light lever check will reveal if a mount has gone soft. If one mount is failing, replace it promptly—letting the exhaust sag can stress flex joints, split welds or cause rattles over bumps.

• Common signs a mount needs replacing: thuds or tapping from under the rear, the tailpipe sitting off‑centre, extra cabin vibration at idle, or visible cracks/splits in the rubber.
• Service tip: inspect mounts at every service interval, in harsher conditions or higher mileage, budget to replace the worst‑affected insulators around the 100,000–150,000 km mark.
• Replacement notes: support the exhaust with a stand, apply penetrating lube to the pegs, and swap one mount at a time to maintain alignment. Use quality rubber insulators specified for the C‑HR, mixing lengths or hardness can pull the system out of line.

Look after these little bits and the C‑HR’s exhaust stays quiet, secure and free of annoying knocks—exactly as Toyota intended.

Popular questions about 2020 Toyota C‑HR exhaust mounts

How do you know an exhaust mount is failing on a 2020 C‑HR?

Tell‑tales include a dull knock over bumps, increased vibration at idle, or the tailpipe sitting crooked in the bumper cut‑out. A quick look underneath may show perished, cracked or elongated rubber insulators. If the exhaust can be moved by hand more than expected, the mounts are likely tired.

How often should the exhaust mounts be checked?

Have them inspected at every routine service while the car’s on a hoist. In Aussie and Kiwi conditions with heat, coastal air and road spray, the rubber ages faster. If the vehicle tows or does lots of short trips, keep an extra eye on them.

Can a DIYer replace the C‑HR exhaust mounts at home?

Yes, if the car is safely supported. Use a stand to support the exhaust, spray the pegs with penetrant, and lever the old insulators off. Fit like‑for‑like mounts to maintain height and alignment. If the system has dropped or there’s a rattle you can’t trace, a workshop visit is the safer bet.
