Morning one and all!

Ever since I had my Wortec Cat-Back fitted, I've had an annoying rattle, well more like a Buzz at around 3500rpm. It's loud and quite noticable (although I didn't notice it before I installed the Wortec).

When you hear it, it sounds as though it's coming from the front half of the car i.e. From the cat forward. Now I'm not to sure what makes up a Cat, but is there anything inside that can become loose and cause such a rattle?

I jacked the car up yesterday and had a good look around underneath and everything seems solid including the heat shields etc.

Anyone had this before?

What car is it? I've had a similar problem where the exhaust rattles a little on mine when the car is warm, having spoke to Monkfish they said it was the 3 way bracket rattling on mine (only the 2004 cars have them) but couldn't find it when I looked.

Sorry for the delayed reply! It's an LS2 Ro smile

Also it happens regardless of whether the car is warm or not, and the whole system seems pretty solid with very little movement.

Had this on 007's car sounded like one of the cats had failed but it turned out one of the lambda sensors was ever so slightly loose

Did have the exhaust apart so may have cured it
