what i meant was will it be as loud and deep as the eisenmann race on the M5? Becoz i never regret putting on the eisenmann on the M5. From the videos, M3 eisenmann race, it is way too soft, compare to the M5. Just wondering if anyone has listen both and what is the major different? I know is a V10 and V8 different but just wana hear out from people who has listen both.
Thanks for the replies though
