When Should You Put an Exhaust System on Your Truck?

Truck owners love how powerful their vehicles are. Trucks need lots of power because they're designed to haul and tow heavy loads without difficulty. However, many truck manufacturers use fairly quiet exhaust systems on their vehicles, despite their powerful engines. If you want your truck to sound as powerful as you know it is, or if you're aiming to reduce the constrictions on the exhaust, then consider adding to or altering your truck's exhaust system.

Fortunately, the factory exhaust system is efficient and doesn't require much modification for you to improve it. The first component in your exhaust system is the exhaust manifold, the part that directs exhaust from individual cylinders into one or two main exhaust pipes. Most exhaust manifolds are pretty efficient and don't require replacement, but if you decide you'd like to replace this part, then you're going to look at a set of headers. A good set of headers will offer a ceramic coating, as well as factory mounting points for sensors. Again, most of the time the factory exhaust manifold is just fine.

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.

Obviously, the most logical thing to do if you want to make a change to your exhaust system is to exchange the factory muffler for an after market one. It'll produce the biggest, most noticeable results. Consider this when looking at after market mufflers:

First, do you want to hear the exhaust ALL the time? In other words, when you drive down the highway, is a little exhaust drone OK? If not, make sure you choose a muffler that's not described as being loud. Check the web and ask your local muffler shop for advice on finding a good muffler. Many muffler manufacturers are even putting sound clips on their websites now.

Second, how loud do you want your truck to be? Do you want something that turns heads, or something that will drown out the neighbours? Extra loud mufflers usually have words like "racing" or "glasspack" in the description, so go for these models only if you're ready to be the loudest thing everywhere you go.

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.

The last thing to consider is exhaust system material. You should make this decision based on where you live. Drivers who live near saltwater will want to invest in stainless steel. It may be more expensive, but it'll hold up again saltwater corrosion for much longer than galvanized or aluminum steel. If you don't live near a saltwater environment, stainless steel will be a needless expense. If rust ever gets into your system, it will take years for you to feel the effects.
