yozzasport exhaust

I've had my yozzasport exhaust on for 18 months and it's starting to develop a vibration noise from the back box and sounds like something inside the back box as come loose just wondering if anyone knows what it come be and has anyone else had this problem.

As above

Also When the car is off kick the back boxes or slap it and see if it rattles then you can tell if its the zorst itself or not.
 
has it shat its baffles out?
Had the car up on the ramp the over week and your correct gouldy it's baffles have gone inside the back box. Have got in contact with yozzasport and he's having a new one made for me so hopefully the car should be back to full health soon.
 
The contact for yozza sport, who is it and how can I get in touch with them?

I need some info and possibly ordering a full mani back system
 
Came home yesterday to find a new yozzasport exhaust. A big thank you to Andrew Hughes (yozzasport) and jp exhaust for getting the exhaust problem sorted so quick.
