the oem back box,Eisenmann sport (not race), and akra back box is great at keeping the rasp down while retaining a deep tone. X pipe mid pipe helps as well, but if u want resonated supersprint and eisenmann has. As for downpipe, AA, redstar, fabspeed, and keller sells hjs dp. IM pretty sure they will be ok to run on whatever power u are going for, BUT they HAVE TO BE HJS. Fabspeed claims hjs cats is capable give 93% of what a straight pipe gives (flow wise).

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. |
