Guys...get a sample pipe built, then make up a batch. We also have our aussie friends to think about.
A33 has the same basic shape, but I think there are small differences...1 - 2 cm is small, but big enough to make it difficult or impossible to fit.

deffy...no prob...gary's bro just did d y-pipe today. the shop is goin to send the OEM y-pipe for mass production...so next time we can just go there n install...good news for all a32 owner!!!

After Y-piped
Mina-san, Good Day.
Here a quick review after installed the Made in Jian Hang y-pipe.
1) F u c k i n g loud after installed it wit my tin kosong straight flow muffler.
The loudness was comparable to a track car. End up with a new S-flow and totally no sound at all at the back.
2) So the back is very quiet now, I can hear clearly the hissing sound from the y-pipe when winding down the windows. But the sound level is considered acceptable @<3000rpm.
3) The thing is different after 4000rpm. U can hear the roaring sound from the y-pipe and all the way up to redline.
4) I noticed the rpm rose faster than before.
5) Sad to say, I feel the low rpm torque is gone. Ah Wah Brother advise to put back a CAT to gain back some low end torque.(my cat was previously replaced with a pipe)
6) Fuel Consumption: Same as before. One full tank about 600+km(included a round trip to Ipoh). I believe this figure is depends on how well you can control your right foot. But be prepared to get lowered FC than before if you floor every gear to redline.
So far so good. I haven't reset my ecu after installed. Will do it soon to see if there is any different.
Verdict:
1) Guaranteed louder if you got a straight flow at the back.
2) Prepare for the roaring sound at high rpm.
2) Even if the performance improvement is subtle or maybe Zero (butt dyno told me got improvement), the workmanship of Ah Wah bro really impressed me.
Ah Wah bro already made a jig so that the y-pipe can be fabricated in shorter time.
With that jig, the piping required lesser welding joints and gives better flow. So no worries mates, satisfaction is guaranteed at Jian Hang.
Photos, coming soon if required.

putting back a CAT will defeat its purpose or not?
i suggest getting a better muffler (if can, same size as stock muffler), then add bullet to subdue d sound.
when i 1st saw ur muffler, i know its goin to be loud. just too small for V6 engine. not enough backpressure. thats why u lose low-rpm torque.
