I don’t have my f90 any longer, as of a couple years ago; however, I ran catless primaries, oem secondaries, with the Remus catback. No fuel smell at all. I learned on previous cars, full catless is not for me anymore. I also remember a deep, even sound with no/minimal rasp. I didn’t run the car in sport plus though, unless racing, as the pops and bangs were too much for me as a daily.
Ran several different aggressive stage 2 tunes and such. Car was quite the performer for me.
