4k rattle

[stevo20]

posted something earlier but think it was over looked so here goes,

what is 4k rattle?

is it when you take the car over 4000 revs and the exhaust knocks against the chassis?

 

[McBunny]

nope its when it gets to 4k you let off the throttle and the baffle in the center section resonates as it loosens up when hot

 

[stevo20]

ahh ok,

what is the prob im getting then?

knocking from the exhaust on the chassis at high revs in first and second, loose joints? exhaust hooks?
