Whenever they hear the term "exhaust service," most Joliet motorists think about exhaust pipes and mufflers. Well, actually, exhaust service at Tuffy Joliet is a lot more comprehensive these days. For example, catalytic converters were mandated in 1976 and on-board emission control computers in 1990. Governmental emissions requirements have forced vehicle manufacturers to come up with much more sophisticated ways to comply with environmental regulations.

Exhaust service has really become exhaust and emissions service. High-tech computer controlled emissions devices are now a big part of exhaust service. Because it is so sophisticated, your auto manufacturer recommends you have your emission system checked out by a qualified Joliet exhaust technician regularly to make sure everything is working right - usually every 6 months or 10,000 miles/16,000 kilometers.

If your Check Engine light comes on, especially if it's flashing, get your car looked at right away. Technicians at Tuffy Joliet in Joliet handle emission problems everyday. You might have exhaust or emissions trouble if your car is difficult to start, runs rough, is noisy or smoking. Call Tuffy Joliet at 815-436-1829 to schedule an appointment if you experience these problems.

Let's review the exhaust system. We will start from the top and start with the exhaust manifold. That is the vital part that attaches to the engine and collects the exhaust from the cylinders and directs it into the exhaust pipe. Exhaust gaskets help seal the connection with the manifold and various other joints along the way. If the manifold is cracked or loose, or a gasket is leaking, detrimental gases could escape into the passenger compartment, where you ride. Carbon monoxide can be deadly, so it is important that your exhaust system doesn't leak. The exhaust pipes connect the various components. They can rust or be damaged by a rock, so they need to be inspected periodically.

Next is the catalytic converter. This part looks like a muffler. It changes chemicals that are dangerous to your health and our Joliet environment into harmless carbon dioxide and water. It doesn't require any maintenance itself. But eventually they wear out. Joliet car owners find this out when their car fails an emissions inspection.

Now the muffler. Its main job is to quiet engine noises. Mufflers work by either absorbing or baffling sound. And you can actually customize your car's sound with different mufflers - anything from whisper quiet to bad-boy rumbley. Rusted or road-damaged mufflers can leak and need to be replaced right away.

The exhaust system is attached to the SUV by a series of hangers and clamps. These fasteners hold the system in place. When hangers come loose or break, hot exhaust components can touch and melt wires, hoses and lines.

Finally, we end at the tailpipe. This is the final outlet for the exhaust. These can be plain-Jane or pretty flashy. Also, the oxygen sensors monitor the oxygen content of the exhaust so the engine control computer can adjust the fuel-to-air mix to keep the car running right.

Exhaust and emissions service at Tuffy Joliet in Joliet covers plain old pipes and high-tech computers. It impacts everything from life and death safety due to exhaust leaks, to fine-tuning the sound of your ride.
