997.2S center muffler bypass with gundo
2009 cabriolet street pleasure driver.
I was originally worried it would get to loud with a modified exhaust but.
I just had the Gundo Hack with 2"pipe done to my OEM mufflers and it sounds much better, noticeable just when you put your foot down.
I think I would like to add a center muffler bypass also and not sure on what design to go with if it matters for HP and Sound
Fab Speed style Xpipe or Sharkworks/ BillyBoat Cross over style.
Thanks in advance

I received a message from Cargraphic regarding the difference between their two X pipe designs, this is the response.
DEAR TOM
HP AND TORQUE GAIN ARE NEARLY IDENTICAL
THE OPEN ONE IS QUIETER AS THE GAS POSTSCOLLIDE ; SLIGHTLY DEEPER SOUND
THE CLOSED ONE HAS A SEPERATED GAS STREAM ANDIS LOUDER ; MORE HIGHER SOUND

This is the exact mod I've done to my 997.2. My only regret is that I waited so long to do it. Perfect sound, no drone, cheaper than replacing entire cat-back exhaust with some aftermarket system. I get compliments all the time on how good the Gundo Hack and crossover pipes sound. Get to it.

Well, I just came across what I wrote 5 years ago and it makes no sense. I can't remember what I was trying to say either. The internet is a weird place.
