Not sure what you mean by that.

Porsche does not claim any hp increase but there must be with a more free-flowing exhaust...maybe 5 hp? I don't know. It may not occur during peak hp on the curve but maybe power doesn't fall off as sharp after peak.

The stock sound does sound wimpy. I read somewhere that Porsche made the stock exhaust louder for the cabs. Get the PSE and do the mod so it's always on. You'll love it.
