bosals on was as loud as no mufflers but with a beter tone(way less rasp)! I lost low end and the ability to feel the car in return I got an intoxicating sound and M3's and C7s to ramdomly downshift on me
6i sounds like a V6 with intak and or exhaust
Not the V6 6 sound but like any ordinary V6 you would come across! Iding the car was real nice! Not shure how the car is w/o resonator on stock mufflers. I only ran stock/bosals/bosals plus cai and for like 1 minute(under 60 seonds) no mufflers. only thing I noticed was lift throttle in a straight without bosals=nosedive.
