C'mon, you can weld cats in, simple, or clamp. I imagine its easiest to put them right after the headers. I don't know, how did the guys who have done it and are running it do it?
I KNOW people on this board have done it, hence Im looking for their feed back.

Do we know what optimum size primaries should be?

Im actually not that worried about cracking as the welds looked pretty good in the pics.
I don't understand the whole "the sky is falling and many babies will die" over asking for real first hand experience with kung pao headers.
That's all Im doing is asking those that have done it who have first hand knowledge with them.
I know nobody wanted to try the pu pu platter cat back. Im sure they were told the system would rust in about 6 months, the muffler would blow out, itll sound like Pu Pu, er I mean crap, and it will damage your engine, and the drone will drive you to batsville. That wasn't the case but the pro tuners were still taking peoples 1500 dollars for a better system indeed. The question is how much better?

Based on my experience optimal size primaries range between 2.00 to 2.25 from the flange straight through to the merge collector. As far as cats are concerned, the oem pre/cats are 400 cell, and if the secondaries share the same part as a 996, they can be as high as 600 cell. Unless you plan on sourcing set of high quality, low cell cats like HJS or Emetec (plan on spending big, big bucks), there's no sense in trying to reinvent the oem set-up.

With regard to the Charlie Chan muffler, understand that I was the one who first discovered it, and later passed the info onto the forum. It's decent design, especially for the money, and to date no one has reported any major problems to speak of.

I have a custom 9ff catback on my vehicle with almost 3.00 inlets and even larger outlets. The sound is ripping, and there's not a hint of drone at any rpm. That said, you get what you pay for.

In any case, I spent extensive time researching and experimenting with different types exhaust components and configurations, to include a catless system. before arriving at my current set-up. I'm happy to pass my advice and experience along to those who are interested in hearing it.
