Hi all,

Had a hayward and scott high flow exhaust system fitted (down pipe, centre pipe and back box) about a year ago followed by a live map. All seemed fine until three weeks after when a metal sounding chatter developed at low speeds. First thought it was wastegate chatter but that has been looked into. Any ideas what causes this? Or has anyone experienced the same?

Cheers

Tolster
