Headers
I am using Manzo headers on a 3.4 996 conversion on my Boxster. 50 MM header
piping and a CAT by pass pipe into a B&B muffler. Runs great and sound good.
It has only been a few weeks but so far so good. I am questioning if my 50MM pipe is large enough for the 3.4 motor and can't comment on durability because of short time involved.
