360 AP Sport Cats on a 99 360

The other day I was getting the car ready for a rally/poker run and when I fired it up, I noticed the distinct smell of rotten eggs. Told my wife that, just to set the ball in motion that there's fixin' to be some money spent....

So, I've been busy researching the 200 cell/100 cell/test pipe products and all the threads I can find. I've settled on a set of `100 cell AP sport cats from James over at Vivid. What I haven't been able to find is info on the cats themselves or too many threads where people have used them; (AP 100 cell cats that is). Usually it's AP headers and "X" brand 200 cell or 100 cell cats.

I had my ECU's tuned by Mase last year, so I need to check with him to see if adding sport cats will change anything. If anyone has first hand knowledge on this setup, it would be great....CEL lights, mini-cats, extenders, performance differences, etc.
