X3 performance exhaust
Did a quick search and didn't find anything for aftermarket exhaust. I have an 07 and would like to see if there are any exhaust mods available for this car. i would love to let it breath and hear it grunt when I step on it.
Also, anyone use the K&N Filter? Did you notice a difference is performance, sound, gas milage, etc.?
