Well I finally did it!!! I had my stock 3.6L mufflers modified
In my research I decided to try the MKII(2002+ muffler) PSE Style mod done to my 2003 996. As you guys know I was thinking about the Fabspeed and maybe Schnell, but in the end the fear of resonance kept me away from both...
I found a shop "Mufflex Performance Exhaust" in Trenton NJ (609-890-0481)which does a lot of custom stainless steel exhaust work and a lot of work on race car systems. The owner Denny is a porsche guy and was pretty excited to do the mod on the mufflers based upon the pictures I showed him.
I will try to attach a sound clip tomorrow, but what I can tell you is the sound is amazing from outside the car. Inside, you barely hear a difference with the windows closed since my cold air intake is so loud to begin with. With the windows down...The exhaust sounds deep and hollow now, like a real sports car, not too loud, just right... exactly like the factory PSE with the baffels open.
I drove it home on the NewJersey turnpike and the car drives the same, no change in anything else other than a wonderful sound when I open the window and floor it....
Attached are some pics Denny took of the work... If anyone is looking to do this, I wouldn't hesitate calling these guys, it was very reasonable concidering they removed the mufflers, did the work and reinstalled them. Less than $400 bucks for everything... I made an appt and waited also...

Shouldn't effect performance at all, it's the exact same thing as PSE with the baffels open. PSE itself is just a modified stock muffler which does the same thing but has a baffel which can be opened or closed electronically. If you have a 99 C2, then you have to do it slightly differently you use a smaller diameter pipe between the intake an output of the muffler or you can buy a cheap OEM 3.6L muffer from a 2002 or newer and have this mod done.

Pretty sure you can isn't the only thing different about the C4S exhaust is the tips which are extended to move closer to the center of the rear bumper.
BTW it doesn't bypass the muffler, just one chamber in the exhaust which is why it's nice and throaty on idle, but when you open it up she screams....
Just noticed your in the NY area, if you want to hear what it sounds like let me know...

With the mufflers on the pre 02 cars you can't tap the muffler chamber, it has too much wadding in it you won't get much sound. With the 02+ they opened it up more at the factory. For pre-02 mufflers, you tie the muffler intake and exhaust together with a small pipe to control the noise level. They have example pictures on rennlist. It's called a MKI muffler mod

Here's a picture from Rennlist on how you have to modify a pre-02 muffler to get PSE sound, though in this case it's identical to the PSE because porsche didn't have an "off" switch (which most people disable anyway on the newer PSE) Notice the small tube and the bend to lower the noise level since it's "Raw" sound coming off the cats...

I tried this before getting my cargraphic cans. It sounded okay I guess. However, after parking next to a car with PSE and revving the motors, it didn't sound half as good as the PSE car. I promptly got rid of them and put some aftermarket mufflers on there. You would think it sounded the same, but it doesn't.
