To connect your Kooks headers to your stock or aftermarket exhaust, you will need a Kooks Y-pipe. These Y-pipes are all 304 stainless and come with the following options-

  • Off Road – Deletes your catalytic converters.
  • High Flow Race Cats – The same catalytic converters the other manufacturer uses. Very high flow, requires a tune to not have check engine lights.
  • Ultra High Performance Green Cats – The best catalytic converter you can buy. Rated for 900HP and flows better than standard race cats. In many cases they don’t throw check engine lights also.
