In the market for a new exhuast.
I've recently decided that I want to put an aftermarket exhaust on my M3 next month and have narrowed it down to 3 choices.
I am thinking either agency power, ss race, or gruppe m. But I am having trouble deciding between the three of them now. I want something thats very loud/raw but still sounds good and will perform well. Price is not a problem. I just wanted to hear what your guys opinions were on these three and what you think of them. Any help with this would be appreciated.
