You can see some of the many, many tig welds holding the muffler together here. There are a lot of labor hours in the creation of the muffler.
You can also see the smaller diameter “quiet” exhaust path contrasted with the larger diameter power side of the muffler here. The Dundon muffler has a lifetime guarantee including track use and is modular, which will work with the stock exhaust.
Looking inside the Dundon muffler, you can see how the quiet side of the muffler leads to the chambers inside the muffler before exiting into the exhaust tips. You can also see how the loud side is nearly just a straight pipe leading to an X- pipe right before the exhaust tip exit.
Here is the exit of the muffler showing the internal X-pipe details. X-pipes help improve mid-range power in general and usually sound better as well.
Here is a close look of the Dundon Mufflers large diameter exhaust terminations.
