This is the Kooks 1.75" Headers for 2011+ 5.0L.
We have just concluded our attendance to the 2011 SEMA show in Las Vegas. Frankly speaking, one of our objectives was to sign a dealer agreement with exhaust"Vendor X".
However, as we had the opportunity to look at ALL the competition in the exhaust business, it was very clear to us that the best and most complete product
offering was by Kook's. The fit and finish of the Kook's header system was just above and beyond that of others. Very thick, precision cut, flanges. T-304
stainless construction throughout. The system is offered in 1 5/8", 1 3/4" and 1 7/8" primaries. We recommend the 1 3/4" for almpost all applications. If you
had intentions of adding significant power adders in the future - namely a supercharger and/or NOS, then maybe you would consider 1 7/8". However, for the best
performance in a normally aspiriated 5.0, Coyote motor, we would suggest the 1 3/4" offered here. (If you prefer one of the other two sizes, just email us after
you have ordered and we'll get you the headers you want.)
We've included several photos of the hand finish work that Kook's performs on each header before shipment. This is just one of the details that sets the Kook's
system apart from the others. Regardless of what primary tube size you may opt for, the collector on each system is 3".
Kook's is the first of the larger performance exhaust manufacturers to offer a COMPLETE "header to exhaust tip" solution - ensuring excellent fitment and maximum performance
gains... as well as a substantial weight savings over stock. Unique to a Kook's solution, Boss 302 owners have the maximum of flexibility!! Following the headers, you would
have your choice of THREE unique mid pipes, and each of these mid-pipes can be ordered with CATS or in an off-road configuration without CATS. Cool Tech is proud to offer
the complete line of Kook's performance products. For the mid-pipe, you can choose to have an H-Pipe or an X-Pipe. But, only Kook's offers an additional H-Pipe that is configured
specifically for the side pipes on the Boss 302. This configuration allows you to keep the Boss 302 side pipes. Please note that the Boss 302 sidepipes are unlikely to add
any measureable performance benefit, but they allow the owner to have some additional control and flexibility to control the sound. By varying the size of the hole in the
side plate block-off plates, the owner can customize the sound of the car... from mild to wild. For maximimum weight savings, owners can choose a "conventional" H-pipe or X-Pipe.
As stated previously, all 3 mid-pipes - H-Pipe 302, Conventional H-Pipe, or Conventional X-pipe (pictured) can be ordered with or without CATS.
