I have watching a show called Bitchin' Rides. One of the cool things they do when customizing a vehicle is to install muffler cut-outs. This allows the driver to hit a button and open a port in the muffler thereby making roar.
I love my BMW Z3 M Roadster, but it would be nice to have a muscle car sound now and then. However, I am concerned that doing so might change the back-pressure and adversely affect performance.
If you have installed cut-outs, what has been your experience?
