Weird clicking sound as I accelerate out of corners.

EDIT EDIT: the car has new axle bearings and brand new front wheel bearings. The driveshaft is tight, not much play at all in the u joints. Transmission is full of clean fluid. The noise only started after replacing my muffler and removing the tailpipe.

How about some more info, about the car. Year, model, engine, trans, rear, etc?
