I have a 2005 4.2 STR. And it need a new pair of cats. Rather than replacing them with stock I would like to fit a pair of performance 200 cell items.

But I want to keep the rest of the exhaust stock, I've kind of grown out of loud exhausts, had several over the years, dont think it suits the Jag TBH.

Does any one know who makes a pair of sports cats that can be used with the existing exhaust system.

Thanks very much.
