Exhaust System Cost – How Much Should You Pay?

When your car starts rattling or you notice a strange smell, the exhaust is often the first suspect. Fixing it isn’t always cheap, but knowing what you’re paying for makes the bill easier to handle. Below we break down the main cost drivers and give you easy ways to trim the price without risking quality.

What Makes Up the Cost?

The price of a new exhaust system is a mix of parts, labor, and the specific make of your car. A basic muffler can run $80 to $200, while a full‑cat‑converter replacement often costs $300 to $1,200 plus labor. Resonators sit in the middle and usually add $100 to $350. Labor rates vary by shop – expect $70 to $130 per hour, and most jobs need 2–4 hours.

Brand matters too. OEM (original equipment manufacturer) parts match the exact specs of your vehicle but carry a premium. Aftermarket options are cheaper and can perform just as well if you pick a reputable brand. Your car’s size and engine type also matter – a small hatchback will need less material than a heavy‑duty truck, so the total can swing widely.

Ways to Cut the Price

Start by getting at least three quotes. Small independent garages often charge less than big chains, and they may have access to the same quality parts. Ask if they can reuse any reusable components, like brackets or hangers, to lower the bill.

Consider aftermarket parts that come with a solid warranty. Many manufacturers offer a 3‑year or 50,000‑mile guarantee, which is comparable to OEM coverage. If you’re handy, a muffler swap can be a DIY job – you’ll need a jack, safety stands, and basic tools, and you’ll save the labor cost entirely.

Keep your exhaust clean and check it regularly. A buildup of rust or road grime can accelerate damage, leading to expensive replacements. Simple maintenance like rinsing the underside after winter or salty road seasons can add years to the system’s life.

Finally, stay aware of any local emissions regulations. Some areas require specific catalytic converters, and installing the wrong type can lead to costly re‑work or even a failed MOT. Ask the shop to confirm the part meets local standards before they start the job.

Bottom line: expect to pay anywhere from $200 for a basic muffler swap to $2,000 for a full high‑performance exhaust on a larger vehicle. By shopping around, choosing the right parts, and doing basic upkeep, you can keep the cost in the lower end of that range and avoid surprise bills.
