here are the pictures of the stock is250 exhaust on MY 350
the picture of the smaller diameter exhaust is my friends car with my old exhaust on it.
sounds decent, a little more bass, not much, haven't driven it yet.
going to test drive it to work tomorrow morning.
Thanks for the input guys, appreciate it
