I just sold my Abarth, they come without reaonators or mufflers. I went 3" catless and exhaust. I think it "fits" the Abarth quirkiness with that type of sound, to me the FISt would look/ sound ridicolous with catless/resonator/Mufflerless. And you wouldnt gain any performance just an annoying drone......
My FiST is orange with stripes -- I'm down to make it loud & obnoxious. The CP-E exhaust has one resonator (right behind the downpipe) and the helmholtz resonator before the tips, so it's almost a straight piped system that is supposed to get rid of drone.
I've ordered mine via LethalPerformance (on Monday) and I still haven't gotten a tracking number. Hoping it just shows up lol.
HPSI has a tune to improve your crackle and pops...... Ferrari 595 tune. Maybe a vendor could chime in, but having the ability to switch from a crackle tune to performance tune wpuld be nice
