Is anyone runnin one of these systems and if so how is the sound? I would like to get a deep loud tone outta my 06 and really dont want to straight pipe, just lookin for a deep throaty sound and heard the MBRP 5' has a awesome sound to it!

 

I got one, and its LOUD!!! But it flipped the muffler, it might be quieter if it was on right....

 

If you want deep go with the cool duals. I have them on my 05 and it took away all of the raspy sound. It sounds more like a tractor trailer now. It doesn't sound anything like any other 3rd gen I've heard. You will lose some low end torque if you're running 5 inch and you're under around 500 hp. There's not enough pressure to keep the exhaust gas flowing fast enough unless you're running a high horsepower motor. The MBRP mufflers are all supposed to be turned in the position where it is louder, with the holes in the louvers facing toward the rear, not catching air. I install these systems all the time and I'm yet to see one that said to put the muffler on with the holes catching air.
