Hi All,

Just have recently swapped an 1jz, vvti, w/o etcs. Unfortunately I couldn't find any exhaust Y-pipe (the one connected to the exhaust manifold) so I had to make one, just to have the engine run silent somehow.

The manifold is 6-2 type. Since I haven't seen any stock pipe and I was in a hurry at the same time, I decided to make the 2-1 part as convenient as possible, so it's about 300mm long. I'm sure that is far from optimal setting, so I had to start this topic.

In short, what I'm looking for is at least a photo of the stock exhaust pipe, though I would appreciate a lot if someone takes time to measure the Y-part.

Next, I wonder if exhaust cross-section of 56mm all the way thru (my current setup) is sufficient for 1jz or not. Any minds are welcome.
