Im partial owning the Race but know Akra very well.... money is not an issue for me and Id still take the E race---- its a set of cans with pipes. The sound is louder, more exotic IMHO with E-Race and this car needs a wake up call big time from the stock exhaust.
on a side note I have the Meister on my M6 F12 and its an awesome piece of work too--- slightly deeper than the E race but less exotic.
