I bought a SS exhaust manifold from a guy on Craigslist but I didn't realize that it didn't have a bung for the O2 sensor or that the 94-99 B18C1's used a slightly different manifold design.

Is it possible for me to buy an adapter to make it work or will I have to take it to an exhaust shop and have them extend it? I've seen references to prebuilt adapters but I haven't been able to find any for sale.

Thanks!

 

You can have a shop weld a o2 bung on the header.

Then they can extend or shorten you exhaust pipe and cat to fit perfect to the header.
