This system will bolt right up to your factory exhaust! Both are made of stainless steel and engineered to the same high standard as Kooks other products!


This system comes standard with one O2 extension which will fit manual Mustang GT's. If you have a automatic GT, you will have to indicate so in the dropdown box above so that you will receive all three O2 extensions needed for the auto.
