Parts for your 2017 Mitsubishi Asx-Exhaust mount

2017 Mitsubishi ASX exhaust-mount: what it does and how to look after it

Yes, the 2017 Mitsubishi ASX is fitted with exhaust-mounts (rubber exhaust insulators/hangers). This is confirmed by Mitsubishi’s factory service information for the GA/GF platform (Exhaust System section), which illustrates multiple support insulators at the front pipe, centre section and rear muffler, and by the Mitsubishi ASA electronic parts catalogue, which lists “Insulator, exhaust mounting” positions for the 2017 ASX. In other words, the exhaust-mount is very much relevant to this model.

On this ASX, the exhaust-mount’s job is simple but important: suspend the exhaust system from the body, isolate engine and road vibration, and keep the tailpipe, muffler and pipes correctly aligned. Those flexible rubber mounts let the exhaust expand and move a touch without knocking on the subframe, rear bumper, or heat shields. That means less drone in the cabin, less stress on the catalytic converter and flex joint, and a quieter, comfier drive.

As these mounts age—especially in Aussie and Kiwi coastal conditions—the rubber can harden, crack or sag. Tell-tale signs include a dull thud over bumps, the tailpipe sitting off-centre or lower than normal, a buzz at idle, or visible splits in the rubber. If a mount fails, the exhaust can contact the body or hang low, risking damage to joints, sensors and heat shields.

Servicing-wise, they’re a quick win. A visual check at every service (or roughly every 20,000 km) is smart, and more often if the vehicle sees gravel roads, towing, or beach work. Look for perishing, oil-soaked rubber, stretched hangers and shiny rub marks on the exhaust or underbody. Replace at the first sign of sag or cracking—waiting can cost a muffler or O2 sensor.

• Replacement tips: let the exhaust go fully cold, support it with a jack and a block of wood, mist the old mount and pegs with silicone spray, then lever the rubber off with a blunt pry tool.
• Refit the new mount in the same orientation and confirm even clearance around the muffler, subframe and bumper. If bracket bolts are removed, tighten to manufacturer spec (or snug and recheck) without overdoing it.
• OEM-style rubber mounts keep cabin noise down, stiffer polyurethane options can last longer but may add vibration.

It’s a low-cost part that pays off in comfort and protects pricier exhaust components on the 2017 ASX.

Popular questions about the 2017 Mitsubishi ASX exhaust-mount

How many exhaust-mounts does a 2017 ASX have?
Most 2017 ASX variants use several rubber mounts—typically at the front/centre pipe and rear muffler. The exact count can vary by engine and trim, but Mitsubishi’s service information shows multiple support insulators across the system. A quick look underneath will confirm your car’s layout.

What are the symptoms of a failing exhaust-mount on an ASX?
Common signs are a knocking sound over bumps, a droopy or off‑centre tailpipe, vibration or buzzing at idle, and cracked or perished rubber. Left too long, the exhaust can touch the body or melt the rear bumper insert, and joints may start leaking.

Can a DIYer replace ASX exhaust-mounts at home?
Yes. With axle stands or ramps, silicone spray, a pry tool and safety gear, a home mechanic can swap them in under an hour. Always work on a cold exhaust and support it before removing any mounts. If alignment looks off afterwards, have a workshop check clearances.
