Kooks 3″ Y-pipe with High Flow Race Cats- 2011-2013 GM 1500 Series Full Size Truck & SUV (6.2L)
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.
