The quickest way to make a truck sound deeper and louder is to remove its muffler, although Pro Exhaust cautions that this is illegal in states with stringent emissions regulations. Another strategy is to streamline the exhaust system and replace the muffler with an aftermarket model designed to amplify the sound of the vehicle. This does not affect the truck's emissions, but does violate noise ordinances in some cities.
According to Performance 4 Trucks, there are three types of replacement exhausts that amplify and deepen a truck's sound. Single-side exhausts are slightly larger than standard factory parts and generate a mild volume increase. They are the safest choice in areas with strict vehicle noise laws. Double-side exhausts drastically increase the sound of the truck. Side exhausts curve around the vehicle's rear tires. Drivers who prefer a more traditional silhouette often install dual rear exhausts. These operate on the same principles as the side exhausts but fit beneath the rear bumper.
For maximum volume and sound depth, Performance 4 Trucks recommends aftermarket exhausts and noise-enhancing mufflers. This combination produces deep, rich, stentorian sounds not possible without replacing both components.
Many inexperienced truck enthusiasts purchase new exhaust tips in hopes of a sound boost. However, AutoAnything states that exhaust tips improve the vehicle's appearance but have no effect on sound.
Begin removing the exhaust muffler of a truck by switching off its engine and disconnecting the negative or black cable of the battery. This cuts off power supply to the truck.
Then, cut the end of the truck's tailpipe till the portion where the muffler is positioned with a hacksaw. If desired, skip this step, although carrying it out makes muffler removal an easier process.
Now, take out the rubber hangers that are attached to the truck's tailpipe. Using a wrench, make the tailpipe's bolts loose, and detach the tailpipe completely from the vehicle.
Next, position a stand beneath the muffler to support it, and detach the muffler's clamp. To gain access to the muffler, snip the inlet pipe. Finally, take out the muffler.
Install the special muffler only after the existing muffler is taken out. Before removing the truck's muffler, find out the state regulations concerning the same, as some states deem it illegal to drive a truck without mufflers.
