In simple terms, your exhaust completes three different functions. It routes combustion gases from the engine, reduces noise, and funnels heat away from the cabin and undercarriage. All three functions are critical to your safety and comfort. When the system is compromised, toxic combustion gases can leak into the passenger cabin, making a failing exhaust much more than just a nuisance.

A poorly functioning exhaust can also create back pressure in the system, which reduces engine power and fuel efficiency.

Here are the main components of your exhaust system:

• The exhaust manifolds collect gases directly from the engine.
• The exhaust pipes connect the system’s components.
• The catalytic converter cleans exhaust gases before they continue through the system.
• The muffler reduces noise.

Hangers and heat shields run the length of the system, keeping components secured and protecting the undercarriage from the extreme heat the exhaust system generates.

Because of the location of most of the components, damage is often invisible until the vehicle is on a hoist. That’s why paying attention to the signs described above is so critical.

Road salt is a typical part of Canadian winters, and it can be rough on your vehicle. Since your exhaust components run along the undercarriage of your vehicle, they’re highly susceptible to rust and corrosion from the extra salt and moisture.

Freeze-thaw cycles during the winter and spring also cause metal to expand and contract, which can accelerate cracks and leaks at joints and welds. Short-trip driving in cold weather means your exhaust system never fully heats up, allowing moisture to accumulate inside and speed up the development of rust from the inside out.

Harsh winters cause exhaust systems to wear out much faster compared to milder climates. That’s why it’s even more important that Canadian drivers stay on top of their regular exhaust inspection services.

Keep in mind that older vehicles and those with higher mileage are especially vulnerable. As exhaust components age, the metal thins and welds weaken, making them more susceptible to corrosion and cracking.

The exhaust system can reach extreme temperatures and produces toxic gases, making this a job that requires professional expertise. Our technicians wear personal protective equipment and use specialized tools to keep themselves safe as they inspect and repair the system.

Because of how serious a problem with your exhaust system can become, we recommend scheduling an inspection at every oil change.
