I’ve updated the link. No need to check with BMS their link says it only fits F80/82, I tested it and it works on F90 base. See pic below with stock F90 tip measurements I took. Basically remove your tips with a mallet on Comp and determine if it’s same size, it should be.. however I cannot confirm as I don’t have a comp package vehicle to test.. if it’s same size this Mod will work. As far as I understand base vs comp difference is just black exhaust tips.
