Turbo back exhaust systems are a great idea , for several reasons

Moving up from 3.5 to 4"exhaust will reduce your exhaust gas temperatures by about 200 degrees.

You will gain approximately, an extra 20 horse power,up in the power band. This would occur at around 70 miles per hour, or normal highway speeds. You also loose a little bit of torque, at low rpm.s, however you will more than make up for this when you install a chip. 

If you are into a throaty performance sound, it's going to sound a little bigger.

Cab Drone is amplified when you install a turbo-back system. When you remove the muffler and cat, overtones from the engine are not cancelled. It can be so loud in the cab that you have a hard time listening to the radio. We have a fix for this. Install a Jones Turbine Muffler, with resonator under the floor boards of the passenger seat. this muffler has 0 back pressure. Your engine will not know it is there. It's an 800 hp NASCAR Muffler with resonator. It actually works quite well.

A turbo back stack system along with a good intake, will really help your diesel breath, while directing the exhaust up and away from everything. It also makes a drastic change in the look of your truck.
