UPDATE: This was for when I was aiming to have a 4AGZE turbo hence the large pipe size, this is now very regretfully for sale.
Over the last few days there has been a strike with a picket line at my work which I was expected to be on, so what do I do? work on my car of course! Anyway I started by moving my original exhaust so it doesnt cross over from one side to the other and also so that it finishes before my diff. This leaves the other side completely free and allows my new exhuast to be fitted all the way to the back of the car. It starts as a 3 inch pipe and just before the diff it reduces down to 2.5 inch, all stainless, all equal length diameter bends and with no burrs or steps or intrusive welds.
It took me like 3 days of tedious work but heres what I ended up with:
thats the 3 inch flex pipe at the front which I am hoping wont melt as I am expecting for part of this exhuast to start glowing red at times.
Heres after it has reduced to 2.5 inch where it goes up and over the diff, this part alone took me so many hours. That handbrake cable will obviously need to be held well away.
Taken out of car, notice the reduction in pipe size, although it looks bad on the outside the inside is nice and smooth and ontop has been ground and sanded for even better flow. On the end of this pipe is where I plan to attach my 2.5 inch stainless magnum stainless straight through muffler. If theres wasnt a turbo at the start of this it would be unbearably loud.
A view from the inside, notice how theres a pair of grind marks on each join to match the pipes together, this is one of the reasons it took so long. As for the top while it looks like thres a step there there really isnt, its just an optical illusion.
I only tack welded it together for now, that because if I weld it fully not only will it be rough and potentially burn though it but it will also be gaurenteed to leave weld protrusions on the inside. So when I can I will be getting a friend to Tig weld everything together.
