Automotive Transverse V6 Equal Length Downpipe

[jakeru]

I made an equal length downpipe (with equal length secondaries) for an automotive transverse mounted V6 in a Nissan Maxima. I did this a couple years ago. It has been running strong. The original downpipe has unequal length secondaries.

To make the required "super tight" bend, I had to cut several pie shaped pieces out of an aftermarket mandrel bent pipe, and weld the remaining seams together. This is just aluminized coated mild steel, with 2" secondary pipe diameter (with 2.5" main exhaust diameter.)

I cut out the half-moon shaped piece out of the side to make an "access window" so I could weld the other side of the pipe through it. I then welded the half moon shaped piece back on as the final welding operation.
