I'm assuming this is the best board for this question, sorry if it's not.
I'm trying to fab up some headers for a V12 powered car and the factory ones are not great. The runners are unequal length, and the way everything combines is questionable. I don't think any effective scavenging takes place.
I'm personally after a smooth equal length sound that will hopefully bring the pitch of the engine note up by quite a lot, and I know I can do this in two ways.
As a note, on both, each runner from cylinder head to the place of merging will be the same /equal/ length in order to get the sound I want. (I know this may hurt performance because it functions as two inline 6s, but hopefully the sound isn't affected.)
One way is to have all 6 runners per bank merge into one collector, which is more than likely going to take up more room and be more difficult to produce and manage, but it will definitely give me the sound I'm looking for.
The second solution is to split the 6 to 3 into 1 and 3 into 1 to then merge those 2 collectors into a single pipe further down. I believe I could use less material this way and it would reduce complexity of building it.
I'd just like to know if the second solution would have a massive impact on the sound, or if because every runner will be the same length anyways, it shouldn't matter at all.
Image of what I mean, though the bottom set of headers do not combine into one pipe.
