You didnt say if it was happening only during the initial warm up of the vehicle or all the time. if it is just during warm up this is not too unusual as long as the engine isnt racing. if it is just a "high idle", say arround 2,000 rpm's its normal. the idle would usually go down as the vehicle reaches operating temperature. when you put the vehicle in gear, you are actually loading the engine slightly, thats why the idle comes down then. when in park the engine has no load on it so it is free to rev a little higher at these times. if it a at a high idle constantly, then i would start looking for sticking throttle cable, binding throttle plates, ect and remedy the problem. this should not have anything to do with the dual exhaust.

One common problem is a vac leak or a sticking throttle plate.
The computer controls idle speed by how much air is allowed into the intake. The idle control valve could be sticking even tho you have cleaned it, or have a faulty motor.

What this sounds like is the throttle position sensor, or TPS. When this sensor goes out, you will experience the high idle that will not taper down. The good news is that they are fairly inexpensive and easy to replace.

In general, yes. This is a carb tuning issue. Another possibility is a vacuum leak somewhere, but most likely, it's a carb issue. You'll typically see your rpm drop a bit when you put it in gear, but that it sometimes stalls out points to a carb issue.
