1.8 8v RSi
car just had its MOT done and they had look at my cat which was coming away from center box. kwikfit told me the connection part was warpped so wouldnt bolt up tight enough to stop the hissing sound completely so i would need a new cat. took it to my local garage they said i didnt need one n sealed up the gap. thing is now, the hissing sound has stopped and been replaced my a horrible metally sound when u accelerate. it sounds nothing liek the system used to. what should be done?
concidering buying a new cat n seeing if that helps. also the reason it started hissing was cause i knocked it hard on a speed bump. so im wondering if the manifold has come loose to(as i seem to have a slight noticable power loss.)
