Would of been a much more efficient system if you cut the centre tips and had them welded in place for looks only, and just ran the Corsa muffler straight dumped like the factory dumps.
Bad idea if your looking for performance

There's only about 24" of piping from the exit of the Corsa mufflers to the Saleen exhaust tips. I sincerely doubt there is any significant loss in hp with this setup but next time I'm on the dyno I will compare the old setup with the new.
Kenny, it's a pretty simple job for any decent muffler shop to handle. IMHO the stock exhaust has noticeable drone doesn't sound nearly as good as the Corsas and you can always weld your stock mufflers back in place if need be.
