I've got the new EBWerks muffled catless 3" and it sounds GREAT! The mufflers are two small resonators (not baffles) placed after the X pipe just before the tips. There is no path in the flow less than 3". These are really well made exhausts, the price is right, and their service is unbeatable.
I'm not making near the power you are but that isn't because of the exhaust; mine just isn't modded beyond a flash.
Others who use this exhaust on the board are pushing over 700HP though with Alphas, etc...

What turbos are you running? K16 or K24..

OT....but
Sorry I didn't meant to say Europipe is restrictive. I meant to say the specific 2.5" system I have is restrictive compared to the various 3" systems out there. A europipe 3" system would be less restrictive than mine. I have had my europipe for almost 7years now and still haven't given it up b/c of the sound it makes. I also easily pass smog STILL and have 60k miles on the system.

With their new slash-cut tips it looks great too!

Your EP2 is 2.75" (70mm) not 2.5" (63.5mm). The stock exhaust has 0.36 Bar backpressure and the EP2 has 0.15 Bar.
I've build the same EP2 with 100 cell cats in full 3" and the backpressure was down to 0.13 Bar. Not a breathtaking difference.
One of the downsides of that 3" version was the straight tips as I couldn't modify the inner hole of the stock oval or dual tips to 3".
The typical layout of a 996 Turbo exhaust remains restrictive compared to the simple straight pipes set-up whether it be the stock 2.375" exhaust or the bigger 2.5" - 2.75" or 3" systems.
There is always a 90° turn after the cat, a U-turn in the centre and another nearly 90° turn ahead of the tips. Those direction changes are the main reason for the backpressure.
Imagine Usian Bolt running the 100 meters and making a 90° turn, a short U-turn halfway and another 90° turn near the finish line, I'm sure his times would be worse.

Then my interpretation was wrong, I'm sorry.
