I have 2 sets of this "flat collector" style - both 1 5/8"
- my first set was acquired circa 1992-3 and i don't recall who from, but i was buying a lot of stuff from Automotion in Sunnyvale back then - i don't believe they were from Europe in any case
- i have an old advert picture from Patrick MS showing this "flat collector" style set was for sale by them - don't know the brand, or mfgr,
- they now sell a different style
insofar as a
source in Germany for 914-6 headers - try this old discussion
posted on Pelican by peterrutt Dec 06:"
We found a guy in Germany who makes replicas of original 911 Rally exhausts. This system has short megaphones with 2" entries running from the standard headers running out to 3" at the entries to the (modified) silencer box. Silencer Box is completely empty, the 3inch pipes run straight through & straight out to the back - they have internal holes to allow some pulse venting within the box.
We race a 2 litre 911 in European FIA races (no noise regs) and also in UK - 105Db max. 2 litre motor on Solexes, 'S' cams, Porsche headers to be legal, but downstream from the headers anything goes.
We had a big problem with gas reversion in the intake section - motor would hardly pull until 5ooorpm. THEN it went well...
With these fitted, almost no reversion, engine now pulls well from 4000 & top end is clean - dyno said 196HP"

I'm pretty sure that those are euro headers
