OBX ITBs trumpet dimension

[edward916]

I need to know the dimensions of OBX ITB trumpets
I need to purchase 32-38mm tall trumpets in place of the 50mm.
clearance reasons

A = 47.5mm
B = 57.0mm
C = 78.4mm

Give or take. Hope that helps.

thanks so much, are you positive the inside diameter is 47.5 and not 45mm?
45mm is standard weber.. maybe 47.5 is OD?

No worries mate. Positive on the 47.5mm, measured with verniers.

that's actually great news.

47.5mm ID is LS1 Chevy aftermarket velocity stack size.
Should be cake to find various heights now! good news indeed
