Should You Put An Exhaust System On Your Truck?

If you're a truck owner, you're probably quite familiar with how powerful they are. Trucks are meant to haul and tow heavy loads without strain, which is why they require so much power. Yet most manufacturers equip their trucks with fairly quiet exhaust systems in spite of their powerful engines. If you want your truck's sound to show its power, or you want reduce some of the constrictions in the exhaust, you might want to consider adding to or changing the exhaust system.

Luckily for you, the factory exhaust system on your truck is efficient, and can be easily improved with just a few modifications. The exhaust manifold is the first component of the exhaust system. It directs exhaust from each cylinder together into one or two main exhaust pipes. These are usually fairly efficient and don't need to be replaced. If you decide to change them though, find a good set of headers with ceramic coating and factory mounting points for sensors. Usually though, the factory exhaust manifold will be perfectly fine for your needs.

After the manifold, exhaust travels through the catalytic converters. These are already very efficient and legally required to be on your truck, so you're much better off leaving these alone. The only time you'd do really do anything with the factory catalytic converter is if you were adding an extremely powerful upgrade to your engine, such as a turbo- or supercharger.

After the catalytic converters, the exhaust gases cool somewhat and enter the muffler. Again, the factory exhaust system is pretty good and the standard mufflers aren't very restrictive. Replacing them usually won't result in a significant hp or torque gain...3-5 hp and 5-10 ft-lbs of torque on average. However, after market mufflers will make your truck sound much better. The rumble you'll hear with after market mufflers is exciting, and well worth the cost. After leaving the mufflers, the exhaust will exit out of the tailpipe. Tailpipe tips are a popular add-on, but they're decorative only, and have no impact on your exhaust system's performance.

Changing the factory muffler on your truck for an after market muffler will make the biggest change to your exhaust system, so it's the obvious move to make. Here are some things to consider about after market mufflers:

First, will you be happy hearing the exhaust ALL the time? If you're not too sure you'll want the background noise to include exhaust drone every time you drive anywhere, try to choose a muffler that's not described as loud. Your local muffler shop and the Internet are useful tools for choosing a muffler that suits your needs. Some muffler manufacturers will even have sound clips on their websites now to help you create that perfect roar.

Second, do you want something that people can slightly hear when you drive by, or do you want something so loud that the neighbors know exactly what time you leave for work every morning? Words like "racing" or "glasspack" usually indicate exceptionally loud mufflers, so watch out for those terms unless you want a lot of attention.

Choosing between a single or dual exhaust muffler is another important decision you'll have to make. If your truck came with a single exhaust, then a single after market exhaust will be enough to keep good performance. If you prefer to get a dual exhaust, be prepared to spend more money in exchange for better sound and look. Make sure your installer works around your trailer hitch, or leaves room for one, just in case you decide to add one later.

Your final decision is which exhaust material system you'll use. The right material for you will depend on where you're located geographically. If it's anywhere near a saltwater body, buy stainless steel. It may cost more, but stainless steel will be a wise investment since the saltwater in your environment is harsh on regular galvanized or aluminized steel. Drivers in dry climates won't really benefit from the extra cost of stainless steel, since it'll take years for rust damage to occur if it gets into the system.
