Fabspeed 996 & 997 200 Cell Sport Catalytic Converter X-Pipe
Fabspeed new 996 and 997 200 Cell Sport Cats have been redesigned into a single piece that incorporates a Lost wax Cast Stainless steel X Pipe to increase power and Torque and then we use 200 cell HJS Race catalytic converters which comply with emissions and No check engine lights. The new X-Pipe Sport cats make an additional 14+ HP/3 Ft. Lbs TQ over the previous design and also sounds more sportier and aggressive. The new design also looks nicer under the car and fits like OEM.
- $1495 and all 6speed members receive a $100 discount (First 3 Buyers will also get free shipping in the US)
- Fits all 996 and 997 cars.
- High Quality T304 SS C.N.C. mandrel bent tubing for maximum exhaust flow.
- High Flow 200 Cell HJS Sports Racing catalytic converters for less restriction and more power and sports car sound. Fits all cars worldwide.
- Simple bolt-on direct replacement for the factory OEM Porsche catalytic converters.

Wow - this is very interesting.
What is the benefit of the crossover pipe?
Would you say this is louder, same or softer than your existing design for 997 (two separate 200 cell cats)?
Many thanks

Still cannot decide on practicality to replace headers. Looking at all those designs of sport headers I do not see (theoretically) a ground for much improvement over stock ones.
Generally they are same design pipes, perhaps a little bit thicker, but just a little bit.

I've been told by reputable sources that the stock headers are pretty good. Replacing them will increase noise and give small small gains, not worth it IMO (unless you're tracking it). The real gains come from the cats and this looks like a nice setup. Can't wait to hear the clip.

Expecting once Fabspeed gets back online, we should get a clip from them...
thanks for the offer! You went ahead and order anyway?!

These will never be CARB legal...didnt stop me though from replacing my cats. Just keep the OEM ones just in case.Dave

Well, as I was looking to replace stock cats anyway I decided to get this one, should be no worse than any other anyway, so when I`ll get it - will record a clip for you.

The X crossover in theory would be fine on a V type motor. The H6 or pancake 6 motors from all that I have read dont respond the same way. From my understanding the X pipe is actually more restrictive on these cars then the non xpipe. With a front engine car the Xpipe is usually 2\3s the way down the exhaust path. With the 911s this isnt the case and the firing order doesnt mix well with the x pipe. For Fabspeed to say it offers an additional 14hp over their non xpipe version of the 200cpi catted pipes seems far feteched.Dave

Why wouldn't they be CARB-legal? By that you mean that they would not pass an emissions inspection? If they don't pass, why use them at all? Or is it just an issue specific to CA?
My concern is how much louder they'd make my Fabspeed muffled car. I'd love to try to get a bit more power by using these and a nice set of headers. But not if it would be much louder. Opinions?
By the way, I've been very impressed with the construction quality of my mufflers. These look like they're built to the same standard. So tempting....

As of X pipe on plain H6 - pipe sits after cats there, so I do not think it will actually have much interference with firing order or else there. I do not think that its presence affects anything much at all, actually, other than making some sound side effects. It would be other story if it would be there before cats, but it is behind. Well, I may be wrong about it, but it did not raise any concern in my head. Do you have any specific reason to suspect it may mess up anything?

If you buy these mods you have two options:
1) Find a smog cert center to 'overlook' it (not likely as smog license is big $$$ )
2) Swap back the original parts, smog it, then put them back on
BTW, new cars in Cali are smog exempt for the first 6 years

My feeling is that improvement from headers on my C2 would be mostly virtual than practical, X51 headers aren`t that marginally different from stock ones, really. I do not expect any real benefit from this mod. Replacing cats to 200 cell actually should make some improvement.
