Exhaust Mountings: Your Guide

A vehicle's exhaust system is a complex network of pipes, catalytic converters, silencers, and tailpipes, all working in harmony to channel harmful gases away from the engine and out of the vehicle. However, this intricate system doesn't just hang loosely; it's supported and secured by a series of exhaust mountings. These often-overlooked components play a vital role in the overall performance, safety, and comfort of your car. If you've ever wondered where to find these crucial parts or why they matter so much, you've come to the right place. This guide will delve into the world of exhaust mountings, explaining their function, common types, and where you can reliably source them.

What are Exhaust Mountings and Why are They Important?

Exhaust mountings, also known as exhaust hangers or exhaust brackets, are essentially the supporting structures that hold the exhaust system in place beneath your vehicle. They are typically made from robust rubber or a combination of rubber and metal, designed to withstand the demanding conditions they face. These conditions include constant vibration from the engine and road, exposure to extreme temperatures (both hot exhaust gases and cold weather), and the corrosive effects of road salt and moisture.

The primary function of exhaust mountings is to secure the exhaust system, preventing it from sagging, rattling, or detaching. This is crucial for several reasons:

• Safety: A loose exhaust system can be dangerous. It could drag on the road, potentially causing an accident or damage to other vehicles. It can also lead to exhaust fumes leaking into the cabin, which can be harmful to occupants.
• Noise Reduction: The exhaust system is designed to quieten the engine's combustion noise. Properly mounted components ensure that the silencers and mufflers are positioned correctly to do their job effectively. Loose parts can lead to increased rattling and booming sounds.
• Performance: While not as direct as engine tuning, a secure exhaust system ensures optimal flow of exhaust gases. Any kinks or misalignments caused by faulty mountings could subtly impede performance.
• Longevity of the System: By preventing excessive movement and stress on the exhaust pipes and connections, good mountings help to prolong the life of the entire exhaust system, saving you money on premature replacements.
• Comfort: Excessive vibration transmitted from the exhaust system to the car's chassis can lead to an uncomfortable driving experience, with noticeable shaking and noise inside the cabin.

Common Types of Exhaust Mountings

Exhaust mountings come in various designs to suit different points of attachment and weight requirements within the exhaust system. Here are some of the most common types:

Rubber Mountings (Exhaust Hangers)

These are the most prevalent type. They are typically made from durable, flexible rubber and often feature a loop or eyelet at one end to hook onto the exhaust pipe and a mounting point at the other, which could be a stud, a bolt hole, or another hook to attach to the vehicle's chassis or a bracket. Their flexibility helps to absorb vibrations and slight movements.

Metal Brackets

In some instances, particularly for heavier components or at specific points requiring more rigidity, metal brackets are used. These are often bolted directly to the vehicle's chassis and have rubber grommets or bushes to provide some degree of vibration isolation. Sometimes, rubber is bonded directly to a metal bracket.

Exhaust Clamps and Straps

While not strictly mountings in the same sense as hangers, clamps and straps are often used in conjunction with mountings or to join sections of the exhaust system. They help to secure pipes together and can provide additional support.

Universal vs. Vehicle-Specific Mountings

You'll find both universal and vehicle-specific exhaust mountings. Universal hangers are designed to fit a wide range of vehicles and exhaust systems, often requiring some modification or adaptation. Vehicle-specific parts are engineered precisely for a particular make, model, and year, ensuring a perfect fit and the correct load-bearing capacity. For most repairs, especially if you want to maintain the original integrity and fit, vehicle-specific is the preferred choice.

Where to Find Exhaust Mountings

Finding the right exhaust mountings is straightforward if you know where to look. Here are the most common and reliable places:

Online Automotive Retailers

This is often the most convenient and comprehensive option. Websites like Simply Car Parts stock a vast array of exhaust mountings from leading brands. You can typically search by your vehicle's registration number, making it incredibly easy to find parts that are guaranteed to fit. The advantage of online shopping is the sheer volume of choice, competitive pricing, and detailed product descriptions. You can often find specialist brands like Febi Bilstein and Blue Print, known for their quality and durability.

Local Motor Factors / Car Parts Stores

Your local independent car parts shop or a chain motor factor is another excellent resource. They often have knowledgeable staff who can help you identify the correct part. While their stock might not be as extensive as large online retailers, they can usually order specific parts for you, often with next-day delivery. It's worth checking out a few different local stores to compare prices and availability.

Garages and Mechanics

If you're having your exhaust system serviced or repaired by a professional, they will typically supply and fit the necessary exhaust mountings as part of the job. While this is the most convenient option if you're already having work done, it might be more expensive than sourcing the parts yourself and fitting them or having a more general mechanic do the work.

Specialist Exhaust Shops

For vehicles with custom exhaust systems or for more specialised requirements, dedicated exhaust shops can be invaluable. They often fabricate their own brackets or can source very specific or heavy-duty mountings.

Choosing the Right Exhaust Mounting

When selecting exhaust mountings, consider the following:

• Vehicle Compatibility: Always ensure the part is listed as compatible with your car's make, model, year, and engine size. Using your registration number is the best way to guarantee this.
• Material Quality: Opt for high-quality rubber or a reputable brand. Cheap, low-quality rubber can degrade quickly, crack, and fail prematurely, especially when exposed to heat and chemicals.
• Part Type: Identify whether you need a simple rubber hanger, a bracket with a rubber bush, or a specific type of clamp. Often, examining the old, failed part will give you a clear indication.
• Brand Reputation: Brands like Febi Bilstein, Blue Print, and others known for OE (Original Equipment) quality tend to offer reliable and durable mountings.

Common Signs of Failing Exhaust Mountings

It's important to be aware of the symptoms that indicate your exhaust mountings might need replacing:

• Rattling or Clanking Noises: Especially when driving over bumps or accelerating/decelerating, you might hear metallic noises as the exhaust system moves excessively.
• Sagging Exhaust: If the exhaust pipe or silencer appears to be hanging lower than usual, the mountings have likely failed.
• Excessive Vibration: You might feel more vibration through the car's floor or steering wheel than normal.
• Visible Damage: On inspection, you might see cracked, perished, or completely broken rubber mountings.

Frequently Asked Questions (FAQs)

Q1: How often should I check my exhaust mountings?

It's a good idea to visually inspect your exhaust mountings whenever you have the opportunity, such as during an oil change or tyre rotation. Listen for any unusual noises. A professional mechanic will typically check them during routine servicing.

Q2: Can I drive with a broken exhaust mounting?

While your car might still be drivable, it's not recommended. A broken mounting compromises the safety and integrity of the exhaust system, risking further damage, noise, and potential leaks. It's best to replace them as soon as possible.

Q3: How do I know which type of mounting I need?

The most reliable way is to identify the part number from the old mounting if it's still legible, or to search for parts specific to your vehicle's registration. If unsure, consult a mechanic or the customer service of an automotive parts supplier.

Q4: Are exhaust mountings expensive?

Exhaust mountings are generally inexpensive automotive parts, especially when bought from online retailers or motor factors. The cost of labour to replace them can vary depending on the complexity and your chosen garage.
