Parts for your 2008 Suzuki Sx4-Exhaust mount

2008 Suzuki SX4 exhaust-mount: what it is, why it matters, and how to look after it

Yes, the 2008 Suzuki SX4 uses exhaust mounts. The Suzuki SX4 Factory Service Manual (2007–2010, Exhaust System section) shows the exhaust supported by rubber insulators/hangers, and the Suzuki Genuine Parts Catalogue for the 2008 SX4 lists muffler hangers and exhaust mount rubbers as service parts. Major aftermarket fitment guides (e.g., Bosal and Walker) also specify replacement exhaust mounting rubbers for the SX4. So “exhaust-mount” is absolutely a relevant, fitted component on this model.

On the SX4, the exhaust mounts are the tough little rubber isolators that hang the front pipe, centre section, and rear muffler from the body. Their job is to hold the pipework in place while soaking up vibration so there’s no droning in the cabin and no metal-on-metal knocks over bumps. They also keep the system aligned so joints and flex sections don’t get stressed.

Over time—especially with Aussie and Kiwi coastal air, gravel roads, and lots of short trips—those rubbers can harden, crack, or stretch. When they start to go, the exhaust can sag, rattle against the heat shields or rear beam, or sit off-centre in the bumper cut-out. That can snowball into split joints, broken brackets, or a failed WOF/rego inspection.

• Tell-tale signs it’s time: thumps over bumps, a new rattle at idle, muffler sitting low or skewed, visible cracking in the rubber, or shiny “witness marks” where the pipe has been touching the body.
• Good servicing habits: give the mounts a look every service (around 10,000–15,000 km), especially before long trips. A quick pry with a flat screwdriver shows if they’re perished or overly soft.
• Replacement tips: support the exhaust with a jack and wood block, spray a little silicone to slide the old rubbers off, and fit quality OEM or reputable aftermarket insulators. Replace in pairs where practical so the system stays level. Recheck clearances around heat shields and rear bumper after fitting.

If the SX4 has started knocking after hitting a pothole, don’t ignore it. A fresh set of exhaust mounts is inexpensive and brings the system back to its proper height and hush. It’s a tidy little job for a home spanner-user, or a quick add-on during a routine service at the workshop.

• How many exhaust mounts does a 2008 Suzuki SX4 have?
  Most SX4 variants use several rubber hangers spread along the system—typically three to five depending on hatch/sedan and AWD/2WD. A tech will confirm the exact count when the car’s on a hoist.
• How often should the exhaust mounts be replaced?
  There’s no strict interval. Inspect them at every service and replace when cracked, sagging, or if the exhaust has started to rattle or sit off-centre.
• Is it safe to drive with a broken exhaust mount?
  It’ll often drive, but it’s not wise. A dropped or swinging exhaust can stress flanges and flex joints, create loud knocks, and risk a failed WOF/rego. Replace the failed mount promptly.
