Well, it seems that my de-cat had freed up so much power, it has blown my back box and middle section. Listen to this http://youtu.be/dP3Gxee7nv8
I love the sound though. Reminds me of an E46 M3 silly as it sounds! But it failed the MOT today so new pipe needed. Booked in to have a custom Longlife system tomorrow. I shall do another video after.
i would take the new exhaust off after mot and go back to old one lmfao
