Hi Roger:
If possible can you provide the ID of the 15-degree, .45 header ?

Thanks,
Dave

I'm needing another header to fit my "2017" OPS .45 marine engine. The stock OPS header is nice, however I need more angle for use in my mono. I believe the stock header is approx 5-degrees, I'm in need of at least 12 or 15- degree's.

The OPS .45 exhaust port OD = 19.00mm (.748 in)
The OPS .45 header ID = 23.50mm (.925 in)

Looks like your A/A .45 header ID may be too small? Hard to believe the A/A .45 engine exhaust port is that much smaller?

David did you get your header issue resolved
