When 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.
The next components which the exhaust gases travel through are the catalytic converters. There’s really no benefit to changing or modifying these, and taking them off is a bad idea. Today’s modern catalytic converter is very efficient and legally required, so it makes sense to leave it alone. You would only consider replacing the factory catalytic if you were adding an extremely powerful engine upgrade, like a turbocharger 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, ask yourself if you really want to be hearing the exhaust ALL the time. If you do, make sure to take that into account when selecting your muffler. If you’d prefer not to hear the muffler in the background as you’re driving down the highway, choose a muffler that’s not described as loud. You can look online or at your local muffler shop for more help on finding the perfect muffler. There are even sound clips on many muffler manufacturers’ websites now so you can hear what your muffler will sound like before you buy.
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.
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.
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.
