Replacement catalytic convertor

[tilly]

I had a flexi replaced on my exhaust by a local tyre centre, and after a year it failed, and split. They charged me £150 to replace it, so I was reluctant to pay that again. So, had a search on the 'tinternet and found a new cat pipe for £120 delivered. No brainer, and cheaper...

Issue is, the cat doesn't come with the studs, to fit to the turbo. Question is, is it usual to reuse these, from the old cat, or do I need to order new studs ??
