Here's the deal.
The 996 makes 300 HP at 3.4 ltrs. 88 HP per liter.
The Boxster "S" makes 250 HP at 3.2 ltr. 78 HP per liter.
It doesn't take a rocket scientist to show that if you can get 996 power out of a Boxster "S" you'd gain 32 HP.
Now the kicker - these headers with no change to the cat or muffler same dimensions but built for a 996 make 318-320 HP with no mods to the DME. (94 HP/liter)
That means that you should be able to get 300 HP out of a Boxster "S".
It ain't rocket science. Well, maybe the headers are but
NOTE: We sell this as a complete solution, from header
through cat and INCLUDING muffler and your choice of tips.
Porsche uses 1-5/8" tubing as primaries, we use 2-1/4. That is
80% more crossectional area.
Price complete with cats and muffler $2995.

Now look at the competition:
Nice design and top notch fabrication, only problem is they are a bit on the small side (note these are not for Boxster "S" or 3.4) and they flow all the exhaust through the 1-3/4" collector vs the 2.1/4" we use. We looked at the Mille Miglia "Performance" muffler a set were attached to on a customer car - 1-3/8" inlets!!!!
Here's the FVD setup, Again, nice design, but too short (16"
and look at those tiny 1-5/8" inlets to the muffler!

need to design the system from a clean sheet.
2-1/4" is the optimal tubing size. 1-5/8 is only 52% of that!
