Exhaust system bolts

[rover4x4]

just thought I would mention.. Other day my D-90 sounded like shit, like it was about to go, tickin and all when the motor was under load. problem was the bolts from the y-pipes to the manifold, I know this has been talked about in the past just thought I would mention it, it might be worth checking on yalls D-90's...... now it sounds like it should all is well for time being.

I just had some cracks welded in my ex.system because mine had been loose and aparently the vibration caused it to crack at the flange.

When you first put on the exhaust the gasket between the 2 shrinks and allows the bolts to get loose, so after putting on an exhaust you have to retighten after a few days.
