blk325i was nice enough to message me today as he was close to where I live. I checked out the exhaust and its decent. Just cruising its very nice. I heard it in the car and outside the car in this scenario and I can see why he has had no issues with cops. Its not bad that way.
But when you open it up it turns into some crazy beast. Its very loud when WOT. a bit to much for my tastes but if someone wants some noise its definitely nice and cost effective way to get there all while keeping it respectable for cruising.
