Stock Exhaust System Removal

Stock Muffler

The factory exhaust pipe was originally chopped off after the muffler to allow for a slammed stance (the stock pipe would not clear the rear axle). You can see the stock muffler and the haphazard cut-off location. 

As you can see in the pictures, the stock exhaust system is routed along the passenger side of the truck and takes a fairly straight course. However numerous bends in the pipe restrict flow, and the stock muffler has the tonal equivalent to sucking the life right out of the engine.

Stock Exhaust

The stock exhaust uses both welded and bolted connections. It is suspended by a series of hangers that sit in rubber mounts.

Instead of removing the exhaust from the hangers and loosening rusty bolts, the removal is facilitated by use of a welding torch.

The whole process of removing the muffler, cutting the hangers, and removing the catalytic converter is completed in a matter of minutes. The exhaust is completely removed starting at the Y-pipe intersection before the catalytic converter.

Y-Pipe Intersection

There is a sensor at the Y-Pipe intersection that is necessary for proper emissions control.

One look at the stock exhaust system and you will see how many bends are used. While such an exhaust can be made cheaply and will easily fit every truck off the assembly line, the crimped bends in the exhaust path obstruct a smooth, even flow.

Of special note is the condition of the stock muffler. The insides were rattling around and it was literally toast after five years of use.
