Picked these up a while back, didn't recognize them.
Just got word they are a good design, probably by company "Steinel's Autoworks".
Fitment is 82-89 944 NA 8v cars. In condition as pictured. Primaries are stainless steel welded to modified stock collector pipes.
No dyno information but they sure look sweet. Very tempted to throw them on my car as part of my "go-faster" project but fear it'd be too much a pain when smog time comes for me to reverse.
Looking to see if anyone will bite at $250+shipping.
