Here are the 3 stages of evolution of the exhaust system on my 997.2 C4S Cab. The first clip is the all-stock exhaust system. It really sounded less-than-impressive, so I then installed the PSE, which gave it a much more aggressive exhaust note and growl. However, it still seemed to lack the sound I was after, so I just installed a set of Fabspeed Sport Headers and 200-Cell HJS Cats. The evolution of the sound is amazing, and I now find myself driving with the top down in all weather (rain included!) just to hear this amazing exhaust note and acceleration. The video clips really don't do the actual sound justice, but given that I had a hard time finding clips with these 3 different set up online I though I'd share clips of all 3 iterations of my system in the hopes that it helps others find the exhaust note they're after. Enjoy the vids, and I'll try to post a GoPro shot of the car under acceleration with this new set up. It's awesome ....

About six months ago I did the Gundo Hack along with the replacement of the center muffler with Billy Boat cross pipes on my '09 997.2 C2. Couldn't be happier!!

 

I did a full Tubi exhaust on my C4S and it sounded similar to headers/cats/sport exhaust😉
