Is the cone filter stock? If not, welcome to Street Prepared. If so, cool...
Cat Back Straight pipe = ultra cheap HP, and an easy swap if you want to take it on and off.
For Street/Autocross pads, Axxis Ultimate, Hawk HP+, Porterfield R4s, EBC Green.
If you actually want to stop, pads will dust, and rotors will wear, live with it.
