Not sure what I am going to do yet, if anything. I want something that sounds a little more exotic, with a little deeper overall tone, but I don't want it louder. I like the quiet of the stock system at cruise. If it rips when I get on the gas...well, that's not such a bad thing !!
If you are interested in hearing the AKRA Slip-on with the Challenge Engineering "Street" X-Pipe http://www.challenge-usa.com/exhaust/bmw/street.htm
, I am a little over an hour away from you. Shoot me a PM if interested.
