Parts for your 2021 Suzuki Splash-Exhaust mount

2021 Suzuki Splash exhaust mount — purpose, care, and when to replace

Based on Suzuki’s technical references for the Splash/Ritz platform — including the factory workshop manual exhaust section, the Suzuki Electronic Parts Catalogue diagrams for the exhaust system, and common aftermarket fitment charts from exhaust suppliers — the Suzuki Splash uses multiple rubber exhaust mounts (hangers) to suspend and locate the mid‑pipe and rear muffler. So yes, an exhaust-mount is relevant and fitted to the 2021-registered Suzuki Splash commonly seen in AU/NZ as a later import.

The exhaust-mounts on a Splash do a deceptively big job. They isolate engine and exhaust vibration so the cabin stays quiet, keep the muffler centred in the rear bumper cut-out, and maintain safe clearance to the fuel tank, rear beam, heat shields, and underbody. By allowing a little controlled movement, they also protect the flex joint and catalytic converter from stress. When these rubber hangers harden, stretch, or split, the exhaust can sag, rattle on take-off, thump over bumps, or sit off-centre at the tailpipe.

Service-wise, it pays to have the mounts checked at every routine service or at least every 10,000–15,000 km. In our coastal climate and with plenty of short trips, the rubber can perish faster. Replacement is straightforward when the system’s cool: support the muffler, lubricate the pegs, lever off the old rubbers, and compare length and hole size before refitting quality OEM-spec EPDM mounts. Replacing them in pairs helps keep the exhaust aligned. Once fitted, confirm clearances — ideally a finger’s width (10–20 mm) from beams, heat shields, and the bumper — and make sure brackets and clamps are snug.

• Typical signs it’s time: dull thuds from the rear, buzzing or rattling at idle, a tailpipe that’s skewed, or visible cracking/splitting in the rubbers.
• Good practice: avoid jacking under the exhaust, let it cool before work, and support the system during mount changes to prevent strain at the flex or cat.
• Parts choice: OE-style EPDM suits daily use, stiffer polyurethane hangers can reduce movement but may transmit more vibration — overkill for most Splash owners.

Keeping the Splash’s exhaust-mounts fresh is cheap insurance. It quietens the drive, prevents knocks that can fail a WOF/roadworthy, and protects the rest of the exhaust from premature fatigue.

FAQs

How often should the Splash’s exhaust mounts be replaced?
There isn’t a strict interval, because it depends on heat cycles, driving conditions, and age. A quick inspection at each service is the go. Many Splash owners see 4–6 years out of the rear hangers, city driving, towing, or coastal living can shorten that. Replace at the first signs of cracking, sagging, or contact with the body.

Can worn mounts cause a WOF/roadworthy fail?
They can. If the exhaust is contacting the body, sitting insecurely, or too close to heat-sensitive parts, inspectors may knock it back. Fresh mounts restore correct clearances and secure support, often solving rattles and eliminating the risk of rubbing through heat shields or bumpers.

Are polyurethane hangers worth it on a daily Splash?
Usually not necessary. Poly hangers are stiffer and durable, handy if the car carries loads or sees rough roads, but they can transmit a bit more vibration into the cabin. For most daily drivers, quality OE-style rubber (EPDM) hits the sweet spot of comfort, control, and longevity.
