Hoping someone can help me here

Currently have a vibrant 4-1 on my b16a2 and when hunting for info on them every website stated it had a 2.5" collector and a standard honda cat wont fit so i ordered a 2.5" decat.

When i tried to fit the decat it was way to big to fit the manifold.

Does anyone know if vibrant did a 2.25" collector on there older manifolds as i cant find any info anywere stating that

Thanks

Michael
