Kooks builds all of their products to the highest standard, and these are quite possibly the best long tube headers you can buy for your 2015-2018 Mustang! This kit also includes header gaskets, header nuts/bolts, and Kooks off-road extension pipes, which are designed to connect your new Kooks long tube headers to your factory exhaust. Quite simply, there is not a better header on the market!

Why Kooks?
-Kooks is known for building the best high end consumer headers in the world. This header is constructed with the below high end features!
-Tig welded with all 304 (aircraft grade) mandrel bent stainless steel construction
-Integrated venturi merge spike for better savaging and less collector turbulence
-Primaries blended into the flange for better flow
