2020 Toyota Hilux exhaust mount: purpose, care and replacement

Exhaust mounts are absolutely used on the 2020 Toyota Hilux. Technical sources including the Toyota Hilux N80 series repair manual (Exhaust Pipe section) and the Toyota Electronic Parts Catalogue list multiple exhaust pipe supports and rubber “insulator” hangers for this model, confirming they’re factory-fitted across variants. Aftermarket workshop guides for the N80 Hilux also call out inspection and replacement of these rubber hangers during exhaust work.

On a Hilux, the exhaust mounts suspend the system from the chassis while isolating vibration and noise. They keep the pipework correctly aligned so it clears the underbody, prop shaft, rear axle and towbar, and protect welds, flanges and the DPF/catalyst from stress as the ute flexes on-road and off-road. Good mounts mean fewer rattles, less drone and longer exhaust life.

As part of routine servicing, they’re a quick visual check that pays off. Rubber hardens, cracks or tears with age, heat, oil contamination and outback corrugations. Beach runs and towing add extra weight and movement. Replacing tired mounts is low-cost insurance against a sagging tailpipe or a damaged flex joint.

• Common symptoms: tinny rattles at idle, clunks over bumps, drooping tailpipe, exhaust tapping the towbar or crossmember, or a faint burnt-rubber smell.
• Fitment tips: replace mounts in pairs/sets on the affected section to keep alignment consistent, a touch of silicone spray helps the pegs slide through, check brackets and heat shields while you’re there.

For most owners, a look at every service or 10,000–15,000 km is plenty. If the ute sees heavy towing, corrugations or water crossings, check more often. If a mount shows deep cracking, is oil-soaked, has gone rock-hard, or the exhaust sits off-centre, swap it out. Genuine-style rubber hangers keep noise and harshness down, stiffer polyurethane or “poly” hangers can add control for lifted suspensions or big aftermarket systems but may pass a bit more vibration into the cabin.

When installing, let the exhaust cool fully, support it with a stand, and make sure there’s clean clearance around the chassis, diff and spare. After refitting, run the engine and watch for movement—no knocking, no excessive wobble. The Toyota repair manual and parts catalogue confirm the Hilux uses several dedicated hanger points front to rear, so getting each one healthy keeps the whole system happy.

Popular questions

How often should exhaust mounts be replaced on a 2020 Hilux?
They don’t have a fixed expiry, but many last 80,000–150,000 km. Inspect at every service, and replace sooner if you tow, hit corrugations or notice rattles or a sagging exhaust.

Is it okay to drive if an exhaust mount breaks?
It might limp short distances, but it’s risky. A hanging section can strain the flex joint, knock against the driveline or melt nearby trim. Secure it and replace the mount promptly.

Should I choose OEM rubber or polyurethane hangers?
OEM-style rubber offers the best comfort and noise control for daily driving. Poly hangers are firmer for heavy off-road or modified exhausts, but can transmit more vibration.
