Pics of Primaries on S&S - Measurements!

[PontiacGT2K]

I put the ruler on a block of wood about the same height as the middle of the primaries, stood up pretty high, zoomed in, took the pic, moved the ruler over the primaries and this is what I got. Should be fairly accurate, considering I didn't change the size of the ruler.

So looks like the primaries are around 1 5/8" outside diameter.

If you wanted to know numbers, why didn't you just ask... here are the actual numbers and pics... and unfortunately the flash sucks, but I don't feel like running downstairs again and retaking the pics...

Primaries are 1.61" or ~ 1 5/8" (1.625")

Crossover is 1.97" or ~ 2"

How aboot some inside diameters eh!

I measured those, too, about a month ago. I have them posted over on 60V6 (somewhere). But I'd say take off about .12" for pipe thickness and go from there....

:P

Wow did I waste my time :mad: Thanks:thumbs:

Here are the numbers I got when I measured them awhile ago:

Primary OD - 1.60"
Primary ID - 1.50"

Crossover OD - 1.97"
Crossover ID - 1.88"

Flange thickness - 0.31"

Odd how the primary size is different.... oh well. The flange thickness is also slightly thinner than 3/8" (0.375")... more like 5/16" (0.3125").

None the less, these headers have huge primaries! I think almost 1/4 inch larger than TOG?

TOG primaries are 1 5/8" (according to their site), so they are the same size.

From talking to John (Aleroboy) he told me TOGs were more like 1 3/8" if memory serves me right....but maybe I'm wrong.
