    are they old school sleeve joints with the U clamp or the modern Audi-Style Sleeve or even flanged joints?

    You probably need some firegum or similar around the joint.

    might need to take it apart and put the paste on the inner surface where they push together.

    Cheers aragorn all done now.should I really have to do all that it was a brand new cat when I changed the other side two weeks ago I didn't have that problem,perhaps it was because I only paid 100 quid for this one and the other one was close to 200 just goes to show the mote you pay the better they are.thanks again
