620 Exhaust Flange Group Buy

**Feeler post**

 

In efforts to get my 620 back on the road, I've discovered that I need to replace the exhaust piping that connects to the manifold - the 2 into 1 section.  I've sketched out a new flange that will accept 1 1/2" exhaust pipe welded onto it and sent the design to sendcutsend for laser cutting.  I plan to order just one for now to make sure my measurements are correct, but if anyone needs this part I can order more once I'm sure it's correct and ship them out to you.  

 

At the moment I'm getting pricing based on 1/4" thick mild steel.  As soon as I get pricing info I'll update this post with it.  

 

It's the same flange as in this post - the Mike Klotz flange design.  I couldn't find any info on whether or not it's offered for sale (the part or the CAD file) so I made my own.

I used one of Mklotz's flanges and it worked well. I had to modify it very slightly as I used a 240sx down pipe.

Do you know if he's still offering these for sale or if he is willing to sell the CAD file for reproduction?
