Is that what you were talking about?

He lost power using the BBK shorties. No other headers were tested. And he did it with everything else stock.

I am a bit surprised that he *lost* power, but I'm not surprised that the shorties did nothing with stock mufflers. The mufflers are the bottleneck. The cat is a problem too, but better timing of the headers should flow more through the cat (More constant flow) unless you've got stock mufflers backing it up.

I want to see a real test with different brands and with free flowing exhaust behind it. I would bet money that at least some of them beat stock by a good deal, with or without the stock cats (Although getting rid of the cats is a no brainer, it's just not legal.)

So, I'm not sold on the shorties are worthless bit. With CAI, cat-back, and a good tune they should do quite a bit. However, I do buy the argument that I should spend my money on those other things first. So, I'll do that :-)
