Message Sure, it is feasibly possible that if you crank on the hose clamps, you could pressure test for "x" minutes at 30psi (although a higher pressure would give a larger margin of safety) without any leakage. But what happens over time as the engine flexes, parts get hot, and pieces move? The couplers have more tolerance (or slop room) to move and cause a leak, for one. I understand why you would produce a 2.5" in the first place, as finding a) material that is close to 60mm (2.36"), and b) finding a bending machine with the proper tooling for 60mm (or similar) are both challenging, and c) getting custom silicone made at a 2 3/8 ID is special order, and all drive the lead times and the costs.

I can't say I have pressure tested your set-up myself, but it seems worth the added cost/labor/energy/engineering to size the system properly, rather then offer something that is only a "close match". Can you honestly say that you disagree with that statement?

Regards,
SS
