Gen 3. 3 SGE. Up till about 1996 I think was 4-2-1 From there on they were 4-1.

I've just done lots of digging about and confirmed that they were 4-2-1 all the way through to the end of the 3S-GE's.

Yep. Spot on as always Red.
They got exhaust gas recirculation, coupla otha things an a different computer.
And a significantly different exhaust sound. My 1996 car with the same cat back exhaust as I have on the later car now used to have an annoying whine. Whereas with the 4 into 1 She actually likes the exhaust note. Even the splots and splutters on down changes.

Interesting about a different exhaust sound with the different header configurations.

When running an aftermarket cat and catback with the stock header system on my gen 2, I had an annoying drone around 100 kph on the freeway. As well as that the exhaust was also just a bit too loud.
Then after I fitted the the Super X set, not only had the drone completely gone but the exhaust was noticeably quieter. So win-win.

Hey Darren. Please post up your thoughts once you put that exhaust manifold on your BEAMS. I'll be fascinated to hear if it makes a noticeable difference. Maybe I'll have to start a 5-6 year search for one too! " />

Ahh thanks Red and Falcon! Some things to think about when I get my custom b-pipe made for my G-Limited.
I recently purchased a Fujitsubo Super EX to modify for my BEAMS engine, then a week later I found (after a 5-6 year search) a Phoenix's Power (Garage Fukui SPL) exhaust manifold in Japan.

Would this explain the slight power drop from post 1996 Australian Delivered SW20s? 1994-1996 were rated at 129kw and the later ones at 125kw.

I think it was probably pollution gear related, to conform to stricter regs.

But generally 4-2-1 = more low down torque
While 4-1 = more top end power

Gen 3. 3 SGE. Up till about 1996 I think was 4-2-1 From there on they were 4-1.

I too thought the Super EX was just for the TYPE I/II SW20s until my friend bought one (second hand) for his 1994 Bathurst. Yes, They are beautifully made like all Fujitsubo products :). Unfortunately they never made one for the BEAMS powered SW20s :(

As for the GEN 3 3S-GE being 4-1, I thought they were 4-2-1 but the b-pipe is different to the GEN 2 3S-GE.

That's interesting.
I have always been told that Fujitsubo only sold the Super X headers for the Gen 2 3SGE, so I just assumed that they wouldn't suit the Gen 3.
I actually run the Super X system on my Gen 2 motor, and it is beautifully made full stainless.
The headers have equal length pipes unlike the stock headers, and are 4 kg lighter too.
I note that my Super X header/exhaust system is 4-2-1, the same setup as the stock Gen 2 system.

I think the stock Gen 3 exhaust system is 4-1.
I note on your link the pics show a 4-2-1 setup.

Hi Reddtarga,
The Fujitsubo Super EX is compatible for both TYPE I/II and TYPE III/IV 3S-GE powered SW20s.
The only difference from memory is the GEN III guys can't use the original heat shield as the mounting spots are not the same.

I had a friend many years ago run a Fujitsubo Super EX on his 1994 Bathurst.

Wasn't the Fujitsubo Super EX manifold made for the Gen 2?
I think the OP has a Gen 3.motor

Cool, send me a PM if you change your mind. I have a Fujitsubo Super EX manifold in storage :)
