When talking about "no restriction," you have a couple of primary routes you can take, each with its own results and level of effort.
1. Muffler Delete (or "Straight Pipe"):
This is the most literal interpretation of "no restriction." It involves completely removing the factory muffler and replacing it with a straight section of exhaust pipe.
The Result: This will give you the loudest possible sound and maximum flow. However, it can often create an aggressive, sometimes raspy tone and a significant amount of "drone" at highway speeds, which can be tiring. Before going this route, it's a good idea to check your local state and county regulations on vehicle noise and emissions equipment, as removing a muffler can be illegal in some areas.
2. High-Flow Performance Muffler:
This is the most popular choice. You replace the heavy, chambered stock muffler with an aftermarket performance muffler. Most of these are a "straight-through" design, meaning the exhaust gas flows directly through a perforated pipe with sound-dampening material around it.
The Result: You get a significant reduction in backpressure and a deep, aggressive exhaust note without the harshness of a full delete. Brands design these to control drone while still providing that performance sound when you get on the throttle.
Regardless of which option you choose, the physical job is straightforward and very doable for a DIYer. Doing this yourself is a great way to save a lot of money over what a shop would charge.
You'll want to make sure the truck is safely supported on jack stands and give the exhaust plenty of time to cool down first. The basic steps are to unbolt the flanges on either side of the stock muffler, slide the rubber hangers off the muffler's mounting rods, and lower the old unit out. The bolts can be quite rusty, so soaking them in a good penetrating oil beforehand is key. Then, you simply bolt the new muffler or pipe section in its place. Most aftermarket options are designed to be a direct fit, making the installation simple.
Hope that helps!
