New Tig welded downpipe

[TGP37]

Just tested the DP and it is air tight. Got the bungs welded in and it fits like....perfect. Though I still need to smooth the weld beads inside the pipe. But at least it shows fantastic penetration for a tight seal. Tig is beautiful when all impurities are removed, I spent time prepping the surfaces and it paid off for this noob...lol



Has 2 O2 ports and an EGT port near the turbine. V-Band flange for the turbine connection.

Here is the turbo bolted to the crossover. I'll get more pics when I pull it out for exhaust wrapping.

And two pics I found of the heads port work. Just mild smoothing with a texture.

Thanks, what really made it was cleaning the steel down well. Being a painter for many years I can appreciate the need for a good prep.

I have the steady hand....unless I drink too much coffee.

I agree on surface prep. I got my crash course doing exhaust work on my truck. 200k+ mile rusty pipe is not easy to weld to unless cleaned properly. After I found that out, that Harbor Freight flux core doesn't do a bad job for what it is. I even got some fresh nickel look to some of it.

Yes, fcaw can be effective with exhaust pipe. The turbo flanged/crossover however, ugh a fcaw just made a mess. Trying to weld an 11ga steel pipe to a 3/8" steel flange was not happening. Too hard to heat up the flange well enough w/o burning a hole in the pipe.

But wow, tig was soo much better then I thought.
