Knocking noise when lifting off - Saxperience

Este_Loca · 5th August 2008, 17:52

on every single journey i make (more distinct on short ones) as soon as i lift off the accelarator i get a knocking noise as tho the exhaust is hitting something. but after giving the exhaust a good play around i cant find it hitting against anything.

anyone had this problem and can shed some light on it??

cheers

I had this on the A1 coming back from TOTB. Mine was a strabge sorta sound and vibrated on the floor a bit. Puzzled me!

i'm thinking the manifold to centre section joint. Theres a couple of springs in there. i think if they aren't done up equally they click. think thats my problem anyway

where the cat joins the manifold

its more likley the heat shield hanging off. if it is just pull it off completly as u dont really need it imo.

fixed it. it was the springs on the centre pipe section. ended up needing a whole new section and back box!

cheers for the help guys
