Unroll crescent rolls, and separate each can into 2 rectangles, pressing perforations to seal. Brush evenly with 2 tbsp melted butter. Stir together chopped pecans and next 3 ingredients; sprinkle 3 tbsp pecan mixture onto each rectangle, pressing in gently. Roll up, starting at 1 long side, and twist. Cut 6 shallow 1/2 inch long diagonal slits in each roll. Shape rolls into rings pressing ends together; place on a lightly greased baking sheet. Brush rings with remaining 1 tbsp butter. Bake at 375 degrees for 12 minutes or until rings are golden. Stir together powdered sugar and maple syrup until smooth; drizzle over warm rings. Cut rings in half and serve.
