SR 4-1 header and MBRP Cat-Back installed
I just installed both of these today :smoking: and I'm not sensing much of a difference power wise. I helped my mechanic put it on and we sealed up everything very tightly so I'm fairly positive I don't have any leaks. I was wondering if I should disconnect my battery for 30 seconds and try and reset the ecu. I do have a RS CAI, but I don't have BBTB or BIM, but I did figure I would notice a slight increase in power.
