Unfortunately for me I don’t have the luxury to be in a lake. Instead I’m on there coast around boats running triple 300’s and big yachts. Thank for the info anyway
I'd say it's tuned well and anything you do won't improve it for the $$ spent. Unless you really want more noise, in which case some PVC plumbing hardware will do that. Glue it well and don't run it dry b/c it'll melt.
