Eisenmann Race is the loudest of current exhausts, except for a straight piped muffler delete.

Here was my volume rating posted in another thread:
0- Stock
1- Akra
7- E Race
10- Muffler delete

All that said, the turbos kill the noise on this car and cabin is super insulated. E Race with stock center pipes is not too loud for daily driving. It sounds phenomenal...just do it
