Boot Mod3 Help!? Bootmod3 Stage 2 or Stage 2 AGG
I have a 435i M Sport and I currently have a VRSF down pipe (catless), VRSF Front Mount Intercooler, Burger Motorsports Cold Air Intake and VRSF Charge Pipe. Is it okay to run 91 Stage 2 AGG? They mention to have a full exhaust system which I don't have but is it necessary to have a full exhaust system? Or should i just run the regular stage 2?
