2012 Subaru Impreza Exhaust Mount: Purpose and Maintenance Tips

The 2012 Subaru Impreza, like most vehicles, relies on a robust exhaust system to direct harmful gases away from the engine and passenger compartment while optimising performance and fuel efficiency. A key component of this system is the exhaust mount, which plays an often overlooked yet essential role in keeping everything secure and running smoothly.

Exhaust mounts are essentially brackets, rubber hangers or bushings that hold the exhaust pipes and mufflers in place underneath the car. On the 2012 Subaru Impreza, these mounts are absolutely fitted and serve several important purposes. They ensure the exhaust system is securely attached to the chassis, prevent excessive vibrations and noise, and protect the exhaust components from damage caused by movement or road impacts.

The exhaust system on the 2012 Impreza experiences a lot of stress from heat, movement, and external forces like bumps or uneven surfaces. Without exhaust mounts, the pipes and mufflers would be free to swing or rattle and could eventually crack or break off. Exhaust mounts act like shock absorbers between the rigid metal exhaust parts and the vehicle's frame, cushioning the system from vibrations generated by the engine and the road. This not only extends the lifespan of the exhaust components but also helps maintain driver comfort by minimising noise inside the cabin.

When it comes to servicing the 2012 Subaru Impreza exhaust system, inspecting and maintaining the exhaust mounts should definitely be part of the routine. Over time, these mounts can deteriorate due to exposure to heat, road salt, oils, and dirt. Rubber components can become brittle, crack, or even detach, leading to a loose exhaust system which can cause annoying exhaust noises, poor vehicle performance and in some cases, exhaust fumes entering the cabin.

Replacing worn or damaged exhaust mounts is usually a straightforward and cost-effective repair. Mechanics will generally check for signs of wear during an exhaust system inspection by visually examining the mounts for cracks and physically testing for excessive play or movement in the exhaust. If any mounts are found to be compromised, they should be replaced promptly to avoid further damage to the exhaust pipes or muffler.

Here are some handy tips for maintaining the exhaust mounts on a 2012 Subaru Impreza:

• Regularly inspect mounts during oil changes or tyre rotations. Quick visual checks under the car can catch early signs of wear.
• Pay attention to any new rattling or clunking noises from under the vehicle, especially during acceleration or when going over bumps. These noises can be a sign of failing mounts.
• Try to keep the undercarriage clean and free from excessive dirt or salt buildup, as corrosion and debris can speed up mount deterioration.
• If you're replacing the exhaust or muffler, always install new mounts rather than reusing old ones to ensure a tight, lasting fit.
• During the replacement, it's important to use OEM or high-quality aftermarket mounts designed specifically for the 2012 Subaru Impreza. This guarantees the right fit, durability and performance.

When replacing exhaust mounts, the process usually involves unbolting the exhaust system from the worn mounts and removing the damaged hangers or bushings. New mounts are then fitted to secure the exhaust back in place. Because the exhaust mounts are designed to absorb vibrations, their correct installation is crucial to prevent undue stress on the exhaust pipes and to maintain a quiet, smooth ride.

Ignoring failing exhaust mounts on the 2012 Subaru Impreza can lead to more serious problems over time. Loose exhaust components may rub against the vehicle's underbody, causing damage or premature wear. Exhaust leaks can develop, creating potential safety risks such as exposure to harmful fumes. Moreover, an improperly secured exhaust system can affect engine performance and fuel efficiency.

To keep your 2012 Subaru Impreza running well and avoid unexpected exhaust issues, it's wise to include exhaust mount checks as part of your regular servicing routine. Whether you're a DIY enthusiast or prefer having a professional mechanic handle it, paying attention to these small but vital components can save money and headaches down the road.
