Here, SpinTech mufflers have been welded all the way around the X-pipe and placed up over the crossmember. After that was done, the crew worked the unit forward into the downpipes.

A hanger bracket has been welded to the topside of the mufflers. This bracket lines up with the stock hanger bracket on the body. The muffler doesn't look like any muffler we've seen. Notice the small holes in the spin traps.  The Dakota kit can be ordered...  The Dakota kit can be ordered with either a dual side-exit setup or a dual right-rear-exit setup. Both pipes extend side by side and exit close together at the rear.  This is a true 3-inch system...

This system is able to monitor both banks near the motor and again further back, which allows you to check air and fuel readings.  After the system is in place,...

Here's the street-legal 3-inch after-cat system. The OE catalytic converters are still used; the new system connects to the back of the main cat. Dual 2 1/2-inch pipes exit out of the side of the SpinTech muffler. The system, which can be either clamped on or welded, provides good sound and a gain of about 15 horsepower.
