LS 1,2,3 Race headers Suit turbo or n/a application, very well made all back purged, egt sensor ports. Fitment is very good and plenty of clearance for the plugs and leads. Can be fitted for forward or rearward facing, Full heat shielding welded in place, would have cost a lot to whoever had them built originally. Not sure what vehicle they were originally built for.
