Those look nice LAT.
Vancity, which headers are those? They look similar to my FS.
Since my car is lowered, that middle tube on the awe would worry me, as I've already scraped back there once.
They all look pretty good.

Toby,
I grabbed a standard set of our headers right off the shelf and took some photos.
I see some issues, but since they are a competitor, I will keep those comments to myself. If you want to contact me directly, please do. We will keep it offline.
We back gas so there is no slag in the runners during welding. Also at the flanges and in the collector we grind down welds for optimum flow and we are sure there is no blockage of flow in the collector. Lastly, our designs also do not cheat radii.
Let me know what you think.

I purchased Cargraphics center muffler delete pipe for 997 GT3 from Gert and the quality looks quite good despite what some rennlisters have otherwise said... maybe their quality was so - so in the past and they just could not live it down?
mine does not have the additional silencers....

Mike, please feel free to comment away on the CGs, they are engine dyno proven and were developed and are used by the best Porsche turbo engine builder in the world so people can make up their own mind
Yours are very pretty, no doubt... I have run my fingers inside and there are no protusions it all seems flat, just the welding is not as pretty as yours I guess ? I just measured the diameter of the pipes, seems to be about 13cm, how does that compare to yours ?

Let me first say that I do not want to start a feud with you or other any other board members. The dialogue that we have had and with Todd has been great. I want to keep it up. However, I am just a little shocked to read what you wrote.
Pretty welds alone do not make a header. In fact that is the last thing we look at when evaluating a competitor product. We first look at the amount of hand finishing inside. Have you looked inside an RSR header or any pro level header developed for upper echelon motorsport? There is zero blockage of flow. That massive weld bead at the flange is a huge red flag alone. Also note the cheated radii in your 3rd picture.
Like I said before, the devil is in the details. Too many get caught up on how headers look on the outside, when it is the inside that counts.
Again, I do not want to start a war, but I just had to point this out. I hope you do not take this as an attack.

Mike, sorry if my post was shocking, I was just trying to keep it light hearted since the pics do not really tell us much and your headers are definitely shiniest and prettiest !
Can you point out where that "weld bead" is ? it may be a trick of the light since I have run my fingers over all the accessible inards and there are no bits sticking out and where there are joins it steps down rather than up (if you see what I mean so no ridges)
No feuding here since there is no real way of testing whose makes more power and I'm sure yours are better finished, I guess my slant is that it is moot just how much is to be gained by that better finishing compared to the fundamental design features which I would think are diameters, length of primarys and the collector arrangement the choice of all these criteria can only really be measured on the engine dyno IMO - not to say yours don't work but for similar money I would rather the ones developed on the expensive dyno

Toby, here in the US the money is not similar at all, even with a discount the CGs were still too much for just headers.
also, where did you measure the 13cm diameter?
btw, I love the sound that the AWEs added to my CG exhaust, which was completely unexpected and for me worth the money even if performance gain was questionable.
