Quality Construction. Manufactured from 1-3/4" mandrel bent 304 stainless steel tubing Kooks Long Tube Headers are TIG welded for strength, and feature a leak-free ball flange design to fit perfectly into the included 3" diameter 304 stainless steel Shorty X-pipe for excellent exhaust flow and performance.

Does this come with the gaskets for the install? Will my factory pipes back to the mufflers work to finish the install?

Kenny

  • Hi, This Kooks Header and Catted X-Pipe Combo comes with all necessary gaskets and you can use this combo with the factory after cat piping or a aftermarket Cat back.
