Raceland exhaust manifold
 

Afternoon chaps.

Just wondering if someone could do me a favour and measure the internal diameter of the primary pipes on a Raceland 4-2-1 manifold. Ie. The end that connects to the cylinder head.

Thanks

My supersprint, measured at cylinder head openings, 45mm wide x 35mm high
Roughly 35mm primaries thereafter

Thanks.

Was looking for 8v in particular, with the circular openings :)
