    I have had one fitted & the car made good power once I coupled up a free flow exhaust to it. They are lightweight & weigh bugger all compared to the standard manifold.

    They sound very hollow noise wise & raspy.

    But you need a descent induction kit & decat, with a good freeflow decat exhaust to get the maximum gains.
