Thanks for posting. Good stuff.

RE #3 - It took me 1000 miles before I figured out the FFR pipes were to loud.
Miles 1-600 -who cares how loud it is? this thing is freaking awesome!!!!!!
600-800 - The pipes are starting to annoy me
800-900 - MY ears are starting to hurt after 30+ minutes drives
900-1000 - I gotta get rid of these freaking pipes. They are killing my enjoyment of the car!
Your mileage may vary.
