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.

The factory exhaust system already on your truck is already a pretty efficient system and doesn`t really need much modifications to be improved. The first part of your truck's exhaust system is the exhaust manifold, which channels exhaust from individual cylinders into larger main pipes. These systems are efficient and don't need to be changed, but if you decide you want to anyways, you'll need a set of headers. Quality headers like the ones you'll want will have a ceramic coating and factory mounting points for the sensors. Most of the time though, the standard manifold is more than good enough.

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, 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 your muffler to be just loud enough for passersby to hear, or do you want a loud that will make people stop and stare? If you're looking for that extra attention, you'll want a muffler with words like "racing" or "glasspack" in the description. Otherwise, these mufflers may be too loud for your tastes.

Also important to consider is whether the new muffler is a single or dual exhaust. If your factory exhaust system came with a single exhaust muffler, then your truck will work just as well with a single after market exhaust system. Dual exhaust systems are more expensive, but you'll get a nicer sound and better look. If you use a dual exhaust, check that your installer works around the trailer hitch and/or leaves room for one so you can add it later if you choose.

Finally, what exhaust system material is best? It's a decision that should be based on geography. If you live anywhere near the corrosive effects of saltwater, stainless steel is the smart choice. While it's more expensive up-front, it will last much longer than galvanized or aluminized steel in these climates. People living in dry climates really don't need to purchase stainless steel - if rust attacks their system, it will be years before anything is damaged.
