I ran the Corsa resonator pipe on my 2018 Raptor - The drone was pretty bad in my opinion. The full extreme kit is too loud and raspy in my opinion.
AWE 1FG and 0FG are identical in terms of sound, just the 0FG includes the tailpipes and 5" tips.
I ran the 1FG after Corsa and loved it. Very little drone and wasn't raspy at all. Idle and cruising around town was perfect. I tried out the 2FG when I got a 2019 and it was great too, a little less sound but absolutely zero drone. I'd highly highly recommend any of the AWE offerings. I've ran them on 4/5 of my last vehicles. (18/19 Raptor, 17 Focus RS & 18 Charger 392).
Let me know if I can help you out with anything. We are authorized Corsa and AWE dealers and have both in stock ready to ship and free shipping is included. Corsa is 15 min from our shop too.
