At this time apply a high temperature sealer to exhaust pipe flare in order to avoid problems due to lack of space later on in the installation. 10. Install passenger side header, loosely so you can attach to the y-pipe. 11. Now re-attach air tube to the header using the hardware provided, for vehicles that are EGR equipped. Then apply High Temperature sealer to the base fitting of the EGR valve and re-tighten the air tube.
