i was bored again, my divided downpipe
well i read nzconvertibles article and have my downpipe and turbo up at college,(i am in the welding program) so i decided to port my wastegate and divide my downpipe. the downpipe is an apexi three inch and the pipe i added is 1.75", I used 1/2" cold rolled steel for the new backplate. it seems like it should work very well with the porting.
i havent added a separating plate to keep the turbine gasses and wastegate gasses seperate, i will do that tomorrow

Good idea but I think you should have extended the pipe from the wastegate further down the exhaust stream, and at less of an angle.
but still what you did is way better than I could have done.
on my to do list is learn how to weld.
found a pic I had.

turbo80cid, why do you say i should have extended it farther downstream? i am just trying to learn things hear, just give me some input. the one you have pictured is awsome, i should mabey have used bigger pipe? but whatever, i was just bored and needed a project for class
oh yeah it is nice to have a machining shop right across the hall!

Im doing the exact same thing to mine as we speak, except Im just open venting it. I used to have a special backplate that closed off the exhaust and had a dump tube for the WG, but I sold it with my old turbo. The piece of metal you used for the divider inside the turbo.. could you make another? If so, PM me, Ill buy it from you. I just dont feel like bending/ cutting that piece myseld

Any clued-up exhaust builder should be able to make you something like this.

I’m no expert but I think the idea is to merge the two exhaust “flows”.
You want a smooth transition of 2 “flows” into 1.
I believe it is best to not disrupt the “flow” immediately after the turbo.
think of a "Y" fitting for a fuel line.

zoom zoom go boom
Personally I think dumping it at the downpipes turn towards the rear of the car would be an easier, more effective design. Just have to put up with the noise.
