Hey bro, I got Bootmod3 stage 1 93 octane, and currently running a bms intake and muffler+ resonator delete. Loving the power and shoots crazy pops but want to go stage 2 soon. Do you think that an fmic is necessary? I'm okay with buying a downpipe and charge pipe, but having to buy an fmic would make me think twice abt going stage 2.
Also, I'm looking at the vrsf catless downpipe but I dont know if I need the 3.5" or 4" version. My car is the 2015 LCI with EWG, vin ending D988624. Any help would be great, thanks!
