Parts for your 2012 Daihatsu Bego-Exhaust mount

2012 Daihatsu Bego exhaust mount — what it does and when to replace it

The 2012 Daihatsu Bego absolutely uses exhaust mounts (also called exhaust hangers). This is confirmed in technical sources including the Daihatsu J200/J210 Series Workshop Manual (Engine/Exhaust – Exhaust Pipe and Silencer removal/installation) and the Toyota Rush J200E Electronic Parts Catalogue, which list the “rubber, exhaust pipe support” components that suspend the centre pipe and rear muffler. Aftermarket catalogues for the J200 platform also specify replacement rubber hangers, reinforcing that exhaust mounts are standard fitment on this model.

On this Bego, the exhaust mounts are small but critical rubber isolators that hold the exhaust system up while soaking up vibration so it doesn’t boom or knock into the body. Positioned typically around the centre of the system and near the rear muffler, they keep the pipework aligned under load, off-road flex, and thermal expansion.

When they age or tear, owners may notice a rattle at idle, a thud over bumps, or the tailpipe sitting a bit low or off to one side. Left too long, a sagging exhaust can stress welds, crack joints, or contact heat shields. During routine servicing, a quick inspection goes a long way: look for hardened rubber, cracks, elongation of the holes, or shiny scrape marks where the exhaust has touched the body.

• Service tip: inspect mounts every 10,000–20,000 km or annually, especially if the vehicle tows or sees corrugations.
• Replace in sets on the same section (for example, both rear muffler hangers) to keep alignment even.
• Use OEM-quality rubber or high-temp polyurethane if durability is the priority, note firmer mounts may pass a touch more vibration.

Replacement is straightforward with the car safely supported. Use a stand to support the exhaust, then lubricate the pegs with silicone spray and slide the old rubbers off. Fit the new mounts in the same orientation, check clearances to the body and suspension, and tighten any related brackets to the workshop manual specs. It’s a quick, low-cost refresh that restores quiet operation and protects the rest of the system. If there’s still a rattle after fresh mounts, inspect adjacent brackets, heat shields, and the centre bearing/underbody guards on the Bego for secondary knocks.

FAQs — 2012 Daihatsu Bego exhaust mount

How many exhaust mounts does a 2012 Bego use?
Most Begos have three to four rubber mounts, typically at the centre pipe and around the rear muffler. Exact count can vary by trim and regional spec. A visual check under the car or a quick look-up in the J200 parts catalogue will confirm your layout.

What are the common signs the mounts need replacing?
Tell-tales include exhaust rattles at start-up, a dull knock over bumps, the tailpipe sitting low or skewed, and visible cracks or stretched holes in the rubber. If the exhaust taps the body or heat shields, the mounts are prime suspects.

Are polyurethane hangers a good idea for the Bego?
Poly hangers can last longer and resist heat better, making sense for rough roads or frequent towing. They’re firmer, though, which can transmit a touch more vibration. For everyday comfort, quality OEM-style rubber is a safe bet.
