PartsBlue carries a wide range of exhaust parts for Canadian vehicles — from OEM-quality replacement components to performance-grade aftermarket upgrades. Whether your vehicle needs a new muffler, a replacement catalytic converter, fresh gaskets, or a full manifold, you'll find the right part here, priced in CAD and shipped from our Etobicoke warehouse with no duties or import fees. Canada's road salt and harsh winters are tough on exhaust systems, so we keep high-demand components in stock year-round to get you back on the road fast.
Exhaust system parts are the components that route combustion gases safely away from your engine, reduce noise, control emissions, and support engine performance. A complete car exhaust system runs from the engine block all the way to the rear of the vehicle, passing through several interconnected components along the way.
The exhaust system does three jobs simultaneously: it expels toxic gases produced by combustion, it reduces the sound of those gases escaping, and it filters out harmful pollutants before they enter the atmosphere. When any one component fails, your vehicle can become louder, less fuel-efficient, and potentially non-compliant with Canadian emissions standards enforced under Transport Canada guidelines.
A full exhaust system includes several distinct parts, each serving a specific function. Understanding what each part of an exhaust system does helps you diagnose problems faster and order exactly what you need.
The exhaust manifold is the starting point of the exhaust system, bolted directly to the engine's cylinder head. It collects exhaust gases from each cylinder and channels them into a single outlet. Manifolds are subjected to extreme heat cycling and are a common source of cracks and gasket failures, particularly in Canadian climates where freeze-thaw cycles accelerate metal fatigue.
Mounted in the exhaust pipe before and after the catalytic converter, oxygen sensors monitor the oxygen content of exhaust gases and relay that data to your vehicle's ECU. This allows the engine management system to adjust the fuel mixture in real time. A failing O2 sensor typically triggers a check engine light and reduces fuel efficiency.
Catalytic converters use a ceramic substrate coated with precious metals (platinum, palladium, rhodium) to convert harmful gases — carbon monoxide, hydrocarbons, and nitrogen oxides — into less harmful carbon dioxide, nitrogen, and water vapour. They are a legally required emissions control component on all Canadian road vehicles and are also one of the more valuable parts on the vehicle due to their precious metal content.
Mufflers are sound-dampening chambers that reduce the acoustic energy of exhaust pulses before they exit the tailpipe. They work through a combination of internal baffles, resonating chambers, and sound-absorbing materials. Performance muffler brands such as Flowmaster offer tuned internal designs that reduce back-pressure while producing a sportier exhaust note.
Exhaust pipes connect the components of the exhaust system and route gases from the manifold through the catalytic converter, resonator, and muffler to the tailpipe. Pipes are available in mild steel, aluminised steel, and stainless steel — with stainless steel exhaust parts offering superior corrosion resistance against road salt exposure.
Sealing components — including exhaust gaskets, flanges, and clamps and hangers — hold the system together and prevent exhaust leaks. Gaskets between the manifold and cylinder head are a high-failure item. Rubber hangers suspend the exhaust system under the vehicle and degrade from heat and road salt exposure over time.
Exhaust headers are an aftermarket alternative to factory exhaust manifolds, designed to improve exhaust gas scavenging by giving each cylinder its own tuned-length pipe before merging into a collector. They are a popular performance exhaust upgrade for vehicles where power gains are a priority.
Not all exhaust parts are built the same, and the right choice depends on your vehicle, budget, and goals.
OEM (Original Equipment Manufacturer) parts are direct replacements that match your vehicle's factory specifications exactly. They are the right choice when you want a like-for-like repair with no fitment guesswork.
Aftermarket exhaust parts are manufactured by independent suppliers — including established brands like Walker (a leading supplier for walker exhaust parts Canada) and standard-grade stainless steel pipe kits. Quality varies by brand, which is why PartsBlue only carries verified manufacturers from authorised distributors.
Performance exhaust parts — from brands like Flowmaster and Vance & Hines — are engineered to reduce back-pressure, improve exhaust flow, and in some cases increase horsepower and torque. Stainless steel construction is standard in this category, providing corrosion resistance and a longer service life than stock mild steel components.
Exhaust part prices in Canada vary considerably depending on the component, vehicle, and brand. Here are typical CAD price ranges based on common replacement jobs:
Full exhaust system replacement — covering all components from manifold to tailpipe — typically ranges from CAD $400 to $2,500+ for parts alone, depending on the vehicle. Labour costs at a Canadian shop generally add CAD $150–$400 depending on complexity and regional labour rates. Ordering parts directly from PartsBlue in CAD means no conversion fees and no cross-border duties, which is a meaningful saving compared to importing from US retailers.
PartsBlue is a Canadian auto parts retailer stocking over 2.5 million parts — including a comprehensive range of automotive exhaust parts — from our Etobicoke, Ontario warehouse. Every part on our catalogue comes from a verified manufacturer or authorised distributor, includes full manufacturer's warranty documentation, and is catalogued by confirmed year, make, model, and trim fitment.
Whether you're a DIY mechanic replacing a rusted-out muffler or a shop owner sourcing catalytic converters for a fleet, PartsBlue gives you access to auto parts across all major categories — from brakes to engine cooling — at transparent CAD pricing with fast domestic shipping.
The main parts of a car exhaust system are: the exhaust manifold, oxygen sensors, catalytic converter, resonator (on some vehicles), muffler, exhaust pipes, and tailpipe. Sealing and mounting components — gaskets, flanges, clamps, and rubber hangers — are also considered exhaust parts.
A full exhaust system includes the exhaust manifold, front pipe (downpipe), catalytic converter, mid-pipe, resonator (where fitted), muffler, and tailpipe, along with all associated gaskets, flanges, clamps, and hangers that seal and support the system.
The three core components of an exhaust system are the exhaust manifold (collects gases from the engine), the catalytic converter (reduces harmful emissions), and the muffler (reduces exhaust noise). All three must be in good condition for the system to function correctly.
An exhaust manifold is the cast iron or stainless steel component bolted directly to the engine's cylinder head. It collects exhaust gases from each engine cylinder and routes them into a single outlet pipe leading to the rest of the exhaust system.
The component that connects to the exhaust manifold is typically called the front pipe or downpipe. It routes exhaust gases from the manifold outlet to the catalytic converter. A gasket and flange seal the connection between the manifold and the front pipe.
The middle section of the exhaust system is typically called the mid-pipe or centre pipe. On many vehicles, this section also contains the resonator — a secondary sound-dampening chamber that works alongside the muffler to reduce exhaust noise.
The three main types of exhaust systems are: single exhaust (one pipe from manifold to tailpipe, found on most standard vehicles), dual exhaust (two separate exhaust paths for improved flow and sound, common on V6 and V8 engines), and performance/cat-back systems (aftermarket systems replacing components from the catalytic converter back for improved flow and power).
You should not drive with a detached or severely damaged exhaust. A failed exhaust system produces excessive noise, can direct carbon monoxide fumes into the passenger cabin, reduces fuel efficiency, and will likely fail a provincial vehicle inspection. It also creates a road safety hazard for other drivers.
Exhaust replacement costs in Canada vary by component. A muffler replacement typically runs CAD $150–$600 including parts and labour. Full exhaust system replacement (manifold to tailpipe) ranges from CAD $600 to $3,000+ depending on the vehicle. Sourcing parts directly from PartsBlue in CAD — rather than through a dealer or a US website — reduces parts costs significantly.
The catalytic converter is the most valuable exhaust component due to its content of precious metals — platinum, palladium, and rhodium. Scrap catalytic converters are frequently targeted by thieves because of this value. OEM catalytic converters for some vehicles can cost CAD $500–$1,200 or more to replace.
