Went down a rabbit hole after finding out they fixed the terrible note of the S55 with an equal length mid pipe and came across one for the E46 M3.
It seems to be very new but has some bold claims and it seems to be made for the euro headers which I have but I said I would never decat ever again, but if this truely changes the sound so much I'll consider it again.
"Below 5000rpm, the exhaust tone is now similar to that of a V6. Above 6000rpm, the tone changes to a scream of a V12!"
"Designed to equalize the header length of BMW OEM Euro exhaust manifolds. "
