google John ashley exhaust in the UK. I got my second gen header by referencing pics and sending him e mails of my gasket. I still had to modify it after the collector but Im happy. BTW I got a second gen. If u got a first gen you could unbolt the pre cat off your manifold, port the stock manifold, and have a local shop weld you a flange and down pipe, so u can go back n forth for emissions. This will also give u a CEL, but who cares u ll b faster for cheaper
