Andrew fitted me with an Eisenmann Race as part of the SBM stage 1 kit last week. Will do a bit of a write up and post some photos sometime soon...but wow, I love it!!!
It sounds amazing and has transformed the car! It's quite loud, but mostly only when you want it to be. The only bad thing I could say is it drones a little bit between 115-125kph. It doesn't sound like a V8 commodore, definately more exotic, my neighbour thought it was a lambo
It looks great and is more aggressive looking than stock, yet still quite subtle as the tips are the perfect size for the car. Quality is 100%, well worth the $
