Now all the components and raw material are catalogued, the fixtures and prints are ready, etc. John Kuhn installed the exhaust, this is the final hookup. After oil cooler and some hoses are done, it’s time for a sound check.

Video of the final install, no sound check yet, though:

I think I found one topic that wasn't debated.Some x pipes are 2 pieces of 90 degree tubing with a section cut out and welded together.That would be a reduction of total volume at the x.Others are formed pieces welded together that increase volume at the x.Does the volume differences change the sound waves?

That infinity pipe probably creates big turbulences and flows very badly, it's shape is extremely anti-flow like.
Look at the poor fools designing F1 exhaust ports and headers. The idiots are using the same “anti-flow” infinity-pipe shape off the head in their exhaust. Fail!

So you think you know more about their exhaust than they do and you've only seen it in a video while they've tested it and modified and tested, etc?

If you're that good, why don't you model F1 cars over the phone or something? Since you can tell better than they can what their parts do just by looking at them? They would have no need for all those millions of dollars if they'd just hire you. Lol

Is this in response to me or naukkis79? For what it's worth, I was attempting sarcasm. I think the shape is fine, and the fact that F1 uses it makes me more confident that the shape is fine.

I don't know, but if I'd have to guess, I'd guess that both reduce noise but the x-pipe that has the smaller minimum cross-sectional area at the merge will reduce the noise more.
