For sale a pair of brand new performance manifolds for jaguar xjr 4.2 supercharged, these are manifolds only and will require you to arrange custom fabricated downpipes with your choice of cats to be made to fit your exhaust system.

They made 31 horse power gain at the wheels when tested against standard log manifolds (no other mods were made at the time to the car only manifolds). Power graph is attached.

Professional fitting recommended as these must be fully torqued down to the head before starting car to prevent any distortion.

Thanks for looking.
