Intake snorkel diameter

[Honcho]

Does anyone have a spare intake snorkel they can measure? I'm considering cutting off the end of the resonator tube and installing a velocity stack. I need to know the diameter of the tube so I can get the correct stack. My Comptech cams are hungry for air and I want to test this theory by replicating the NA2 intake tract, which pulls air from both the front and rear of the snorkel, at least the JDM cars.

It's interesting, the resonator tube does not have a uniform diameter. I would say the outer diameter is about 2.50 inches with a wall thickness of about 0.085 inch.

Thank you both!! Now I need to find a 2.5 stack or use a 3" and find a 2.5 to 3" coupler.

Do you still hear an induction honk with current setup?

Yep. My logs are showing a manifold pressure drop above 5000rpm
