^^that too, I forgot he makes those.
You could also get a cast dump pipe from a BPT motor, for a VJ20. it has the same turbo side flange. its much wider inside and will flow a ton better. Josh is running one.
They're a little harder to come by but go for around $50-60 shipped on Clubprotege - You'll still need to fab the rest of the downpipe & possibly fab a flange to connect it to the dump - but its a nice easy 90* bend.
Here's the VJ20 dump & downpipe I made on my BP+T
