I did the 4in mbrp 4in side exit and I hated it (super loud). So I took it off and then got the Borla touring. The Borla is a deeper sound, but not very loud. So if anyone wants a MBRP and loves the loudness I have one in near new condition.
I have been comparing my first AB data to the most recent. That stuff is weird. I think when I tried to fix the lost radio tuner and out the original AB from July I was almost able to apply the 1.7.1 APIM usb from FDRS. It at least saw the data on the drive. Then I screwed up everything.
I did have more issues in forscan with nano than with super cheap off brand elm device. I might need someone to tell me how many modules I updated so I can apply older as built data. I only did a two day licence.
