As far as JayG's concern regarding deleting an emission component it is a fair topic to be discussed. During my searches on the topic I found that the Boxsters with the Top Speed cat delete pipes would still pass a smog test where a sniffer was used. I appears that the upstream cats are efficient enough to keep the emissions within compliance. You will fail a visual inspection though.

Thanks Chuck.

Where do you find a smog shop that will pass the car with the downstream cats removed?

Also, I meant to say before, IMHO, obnoxiously loud cars belong only at the track, not on the street. It really sucky to be driving with my top down and get blasted by a really loud exhaust so I can't hear anything else. the driver does not hear how loud and annoying it is from behind or to one side
