[CHITOWN1series]

When i bought my 135i, one of the first things I began looking into was an exhaust system. After much research, I decided to go with the quad setup (in March of 2012). Out of the quad choices (not very many) I chose the Eisenmann race.

However, I want a louder exhaust and I was just looking to get some thoughts on whether some of you think it is worth it to switch to a berk race.

Currently I have AR design catted downpipes, berk resonated mid pipes and the Eisenmann quad race exhaust on my car with a icarbon carbon fiber quad diffuser. So switching would mean i need to find a new diffuser as well.

Any thoughts on this would be appreciated. Also, I am open to ideas about other exhaust systems. Just trying to see what my options may be. Thanks.
