Walker Exhaust

walker mufflersWalker exhaust has enjoyed a long and enviable association with the automotive industry for over 100 years. From making jack stands for the original Model A’s to exceptionally quiet exhaust systems for today’s demanding cars, Walker Exhaust has a reputation for innovation and excellence.

Walker Exhaust is known for a number of industry firsts, including the very first muffler (known as a louvered tube) in 1932, the first stainless steel muffler in 1941, the first aluminized steel muffler in 1943, the first catalytic reactor system in 1963, and working in conjuction with the Environmental Protection Agency (EPA), Walker Exhaust created the first aftermarket converter in 1978. In 1997 Walker Exhaust offered their now famous Safe and Sound guarantee, which lets consumers return any product within 90 days, if not 100% satisfied.

How Does a Catalytic Converter Work?

A gasoline engine yields an imperfect chemical reaction when gasoline is burned and there are leftover byproducts from the combustion process — some of which can damage the environment. The most damaging pollutants include the “terrible trio” of carbon monoxide, unburned hydrocarbons and oxides of nitrogen.
What Is The Terrible Trio?

Carbon monoxide is a poisonous gas that is odorless and tasteless and can cause multiple health issues, including death when breathed in sufficient quantities. Lots of cities have spikes of carbon monoxide levels in the winter when people idle their cars to help them warm up prior to driving.

Oxides of nitrogen are similar to unburned hydrocarbons in that they can hurt crops as well as aid in the formation of smog.

These by-products of incomplete combustion are such a problem that catalytic converters came into existence to help reduce the pollutants spilling out of the tailpipes of millions of cars.

Once exhaust gas enters the catalytic converter, a catalyst becomes superheated and is able to re-ignite the gasses, causing them to be burned again. The upshot of this process of heating and re-igniting the exhaust gasses is that more of the harmful gasses are burned up in the catalytic converter and the vehicle emissions are reduced.

One thing to keep in mind is a catalytic converter needs to have unleaded gas used in the engine. The lead in leaded gasoline will easily corrupt the sensitive catalyst inside the catalytic converter and render it useless. Interesting enough, the first year that unleaded gasoline was introduced in the US, was also the year the American cars first saw catalytic converters installed.

When Does A Converter Need To Be Replaced?

An aftermarket converter can be installed in only 3 situations:
1) If no converter is on the car when inspected.
2) A state or local inspection program says the catalytic converter is damaged or had lead poisoning or determines it needs to be replaced for any other reason.
3) The Original Equipment warranty is up. That typically occurs on vehicles with more than 80,000 miles or after 8 years.

Most exhaust systems wear out from the inside out. The harsh chemicals in the exhaust gasses contain acids and other caustic brews that will eat away at the inside of the system. In addition, the harsh outer environment — especially nasty winter weather with salts and other chemicals applied to roads, will eat away at the exhaust systems from the outside!

Over time, the double action of inner and outer corrosion will cause the materials to fail, and your car will get loud and inefficient. It’s easy to know when to replace your exhaust system — since it will be hard to hear yourself think over the noise.

You’ll find Walker Exhaust to be a great source for aftermarket catalytic converters and all your other exhaust needs. From the engine to the tailpipe, from economical to high performance, Walker Exhaust supplies all the fittings and equipment to keep your ride safe, quiet and environmentally responsible.
