Sorry to be so slow in responding to this - a bit late in catching up on
e-mail.
I needed a new set of headers about 3 years back when I switched from an
1147 to a 1300. I had a set of Stahl headers, but they were very old
and beat. My frame and bellhousing had already been notched to fit
them. I called and talked with Jere Stahl. Bottom line was he told me
to call around and look for a used set - didn't want to be bothered
with making a new one for me. I also tried a set of Pace headers, but
they are for a street car and hang too far below the frame to work on a
race car.
I ended up having a set of 4 into 1 headers custom made for me. My
engine builder gave the specs to the fabricator and I set him up with a
dummy engine/gearbox./frame to work with. It wasn't cheap, but they
seem to work really well. I do have an extra header flange as I had
them cut out two just in case. My car is HP legal, limited prep.

I was looking at the various Spit engines in the paddock but I forgot to
ask what kind of headers people were using. My car came with a set of Tri-Y
and I replaced them with a new set two years ago. My understanding is these
style help with low to mid range power. After getting passed, at a very
good clip, on the RA straights last weekend, I'm looking at ways to get
more power and still have the car SCCA H-Prod legal. Headers / exhaust
system are one of the few areas where Prep level 2 engines are given free
range.
I'm thinking about a 4->1 style, like a Stahl, which I heard is better for
top end. Any input is appreciated.
thanks
