VERY good info! Nice trick!
I went with the UNI 2 stage red dudes. I was concerned about the heavily increased airflow of running it with a thin element so these UNIs have me confindent Ill be able to do some accurate tuning. They have a bend in their flange, and I also used part of the flange from the old airbox. Looks awesome. Theyre huge though ha. It looks like those harley flat trackers with the two massive K&Ns sticking out. Gangsta gangsta.
Cant wait to see some updates of your bike bro - Ive got a bunch done but havent added photos yet, so Its all talk until I do!
