I'm getting a drivetrain vibration in 4th gear when coasting or maintaining speed around 40 MPH. The vibration comes in short waves (or pulses) about 0.5 to 1.0 seconds "on" and then "off" for the same amount of time.

It's not severe but it does bug me. I'm wondering if the DTS has anything to do with but I haven't had a chance to remove it yet to see. The DTS is the only mod I've done to the car in the 2 months I've had it (no aftermarket snub mount). No unusual vibrations in any other gear or speed.

Anyone else experience this?

nope...but sounds like the chicks will dig it.

Is your sunroof open?

problem has been anything from unbalanced tires, drive shafts and even tranny problems. Nine out of ten times it is the tires are improperly balanced.

No, it's not.

We had our OEM Goodyears replaced under warranty because of uncorrectable vibration and then switched to Pilot Sport A/S in 245/50; the latter were dual-plane balanced on a Hunter machine, and the vibration never returned.
