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.
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.
As they leave the catalytic converters, exhaust gases will cool down a bit and enter the muffler. The factory mufflers usually aren’t too restrictive, and replacing them won’t make a huge difference in the amount of hp or torque you get. The average change is about 3-5 hp and 5-10 ft-lbs of torque. After market mufflers, however, will make a dramatic change and are definitely worth the money. Your truck will sound much better! After the mufflers, exhaust exits the truck via the tailpipe. You can add tailpipe tips to this part, but it’ll be purely for decoration purposes, and won’t affect the exhaust system in any way.
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, 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.
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.
