Parts for your 2018 Suzuki Splash-Exhaust mount

2018 Suzuki Splash exhaust-mount: purpose, care, and when to replace

Based on the Suzuki Splash Workshop/Service Manual exhaust system section and the Suzuki Electronic Parts Catalogue (EPC) for Splash/Agila B platform models, the vehicle’s exhaust is supported by multiple rubber insulators/hangers (commonly called exhaust mounts). These mounts appear in the factory diagrams alongside the front pipe, centre section, and rear muffler, and are specified across K10B and K12B petrol variants. Equivalent diagrams in Opel/Vauxhall Agila B technical literature (the Splash’s twin) show the same arrangement. So, an exhaust-mount is absolutely fitted and relevant on a 2018 Suzuki Splash.

On a 2018 Suzuki Splash, the exhaust-mount’s job is simple but crucial: keep the exhaust in the right place while soaking up engine and road vibrations. Those rubber hangers let the system move slightly as it heats, cools, and flexes, stopping the tailpipe from knocking the rear beam or floor, protecting the flex joint and catalytic converter, and keeping noise down inside the cabin. Most Splash setups run three mounts (sometimes four, depending on variant and market): typically one forward of the centre section and one or two around the rear muffler.

Because they work hard and live under the car, the mounts can harden, crack, or stretch—especially with coastal exposure that speeds up corrosion. Tell-tales include a rattly exhaust at idle, a thud over bumps, a droopy tailpipe, or visible perishing of the rubber. As part of regular servicing in Australia and New Zealand (say, every 12 months or 15,000 km), a quick visual check under the rear and mid-section is smart. If a mount looks tired, replace it—ideally in pairs—before it lets the pipe bang around and damages brackets or the muffler seam.

Replacement is straightforward, but let the system cool first and support it with a jack stand. A spray of silicone lube helps the new rubber slide on. Stick to OE-style rubber or quality equivalents, overly hard “universal” or race polyurethane hangers can increase cabin vibration. If a metal hanger or bracket is bent or rusty, sort that at the same time. After fitting, make sure the tailpipe sits centred in the bumper cut-out, there’s clearance around heat shields, and nothing touches the subframe or beam. A few minutes spent aligning things right will keep the Splash quiet and happy for ages.

• Look and listen: rattles, thumps, and sagging tails are top clues.
• Inspect annually, replace mounts showing cracks, splits, or elongation.
• Recheck clearances after fitting and after the first warm-up cycle.

How many exhaust mounts does a 2018 Suzuki Splash have?

Most Splash models use three mounts: one around the mid-section and two around the rear muffler. Some versions may show a fourth, depending on trim and market parts listings. A quick look under the car will confirm your exact setup.

What are the signs my Splash’s exhaust mounts need replacing?

Common signs are a rattly or tinny noise at idle, a thud over speed humps, or a tailpipe that sits lower than it should. If the rubber looks cracked, perished, or stretched, or if the exhaust can be wiggled enough to touch the body or beam, it’s time to replace.

Can I fit harder polyurethane mounts to my Splash?

You can, but be aware stiffer mounts often send more vibration into the cabin. For day-to-day commuting, OE-spec rubber is the sweet spot. If you’re chasing tighter control, choose a reputable brand and be ready for a little extra NVH.
