Fun fact.. and I couldn't believe it, but the new Ford Mustangs have some sort of pipe-age that pipes the sound of the exhaust into the cabin so the driver can better appreciate the sound of the car. When cleaning things up and making things more efficient, its the first thing guys remove. Good grief! Im really getting too old for this s!!!!.
It reminds me of piping an efficient government into your head so you have this false conception that everything is sounding RIGHT ON MAN! lol.
