Staying in GT4 competition for 2020, Siljehaug switched to the GT4 America SprintX series with fellow KTM-fielding team Marco Polo Motorsports.[13] In his first season in the series, Siljehaug took overall wins at Sonoma and Road America, as well as four other Silver Cup podiums to end the year fourth in points.[14][15] During 2020, Siljehaug also made a one-off return to ADAC GT4 Germany with McLaren-fielding Dörr Motorsport at the Red Bull Ring.[16] Returning to Reiter Engineering for the following year, Siljehaug raced with them in select rounds of the 24H GT Series in the GTX class.[17] Racing a KTM X-Bow GTX Concept, Siljehaug scored wins at Mugello,[18] Le Castellet and Barcelona to secure runner-up honors in the class standings.[19][20] During 2021, Siljehaug also raced for Marco Polo Motorsports in the first three rounds of GT4 America,[21] taking a class podium at Sonoma,[22] as well as making a one-off appearance in Super Super Trucks at Long Beach, taking pole for race two.[23]
