I have a 2003 911 996.2 C2
I am curious about the PSE exhaust. The PSE option was to add a pipe to the capped-off area on the muffler and run it into the other exhaust pipe. Has anyone tried to run that added pipe straight out the back along with the other exhaust pipe? Thus having two exhaust pipes out of one muffler.

Well, the Fister Hack and/or Gundo Hack achieves a good sound and nearly the same objective. This is what most folks here do if they want PSE full time, without the added expense or complexity of PSE. I suppose you could try what you are suggesting, but it would be super custom and although unproven, I cannot think of any downside.

But... why? It seems like there would be nothing or very little to gain (power-wise) by eliminating the "Y" into the exhaust tip.

They actually came both ways, near as I can tell the earlier cars had the one that rejoins clear at the exhaust tip, the later cars look like the pic above.. (I have these.. )

The 996.1 had these


996.2 had the ones posted earlier and the 997 PSE has the additional pipe.
