I'm really leaning the AH route for my car. I was going to hook up with Raffi to hear his car and imagine what it would sound like with the headers and AWE cats. Maybe a tad overkill. This combo was insanely loud with the Fabspeed MBP.

Dave- West side baby! Love it out that way, North Shore right around the corner and all..
I would say the AH will be really loud with 200 cell cats just by the nature of the freer flowing cats. I can't see the headers making a big diff in sound increase, but cats yes. The AH are designed for max performance improvement with stock cats (per vendor)- Which is what I initialy wanted becuse I (ideally) didn't want to mess with changing cats due to CA smog BS..
Bypass pipes will be crazy loud even with stock cats. I would say the AH are 60% quieter than bypass pipes inside the car, 60% quieter outside the car at idle / cruise, and 20% quieter outside the car at WOT- But this is with stock cats. I played with a set of bypass pipes before putting on the AH, too much. The AH's only get insane when you put your foot in it and even then buffers the sound passed into the cabin.
BTW I'm happy to give you a demo if you are ever up West LA area!

I live in Playa del Rey near Marina, can't get more Westside than that..
I have a set of MBP that I put on the car with the 200cpi cats, within 6 hrs. of doing so I was pulled over for excessive noise. I know surfingbuddhist had them on his car with 200cpi cats.

Sorry we missed eachother today. Tomorrow I think Terry is in as well- he has a great "test track"/ abandoned road we can use. We will make vids showing:
-997S with EVOMS and Fabspeed (ATL-Porsche)
-997S with EVOMS and AfterHours (CATTMAN)
-996 C4S with EVOMS, AfterHours, and 200 cell cats (Brando)
If we can get this done Sunday, I can do all the editing and make a great video to post for everyone on youtube.
