I may be data logging this weekend, its hard for me to do since I need to dodge the cops when I take the car out because its not street legal. I live close to an event center and I will be speaking with someone there to see if they would let me use there parking lot for an afternoon.

It drops down behind the manifold by the dip stick, then goes down and connects right before my flex pipe in the end of the down pipe.

Walking the cup is accepted way of welding pipe/tube via TIG,I just dont like the way it looks,But it ties the pieces together better...thats per the AWS specs.

It's really not needed for these small pipes though. A straight root & cap, or even a single pass with a good bevel is fine. Walking the cup covers a wider gap, that's the main advatage.

Any pics of the dump tube routing? I'm having a hard time picturing it. It's a pretty tight fit back there. Did you have to curve it under the runner?

Lol, that's only a small section, anyone could do that. Getting the entire mani to look like that is almost impossible. What type of TIG machine are you using?

I have a Lincoln invertech 205, I did the collector in a single pass but wanted more material there when I put the waste gate on, thats why it looks like that. Ill try to get some pics latter it was very easy, it follows the top of the down pipe all the way down.

I like using stringers, much easier to know when you have penetration vs weave. I weave thick pipe over 4" just because it looks sweeter and less of a chance of slag inclusions because your burning it in.

I can see the penetration, I just felt like it was thin in that area because of all the angles and wanted to beef it up so I went over it until The whole area was filled in.
