So just one point to circle back on this as I specialized in flat six exhaust for the last 25 years. The reason for poor vacuum signal was/is the header size. Back when Richard Parr owned PMO he called me and asked that I stop selling 1.625 headers to folks with engines smaller than 3.0 and it wasn’t once but multiple times. The PMOs had such a poor vacuum signal with larger primaries the cars ran terrible down low and would idle terribly.


Otherwise carry on looks like you’re doing a nice job.
