Chris,
I am not sure if you sell intake parts separately or you only sell complete systems. I hope you don't mind me asking. I am looking for a black silicone, 90* elbow/adapter. It needs to have a 3 1/2" I.D. on one end and a 4 1/2" I.D. on the other end. Please let me know if you sell an elbow like this and how much $ it would be . If you don't have or don't want to sell separately, could you please provide a link to a supplier that I could try?
Thanks for your time,
Dan
