I guess I am part of the 'boring' crowd of Stinger owners now b/c I do not like the PSSSST sound. LOL ...The main limiter on the stock intake setup is the baffles/boxes *in front of* the core support. Remove those, add a snorkel if you want, and you're 90% of the way there. An aftermarket intake gives you the PSSSST and a bit more power.
Those forward air boxes are there to muffle noise, but they also seriously restrict airflow.
