Greddy Kit on 6th Gen Civics

[Racing Rice]

Ok, I went to a shop today and asked about getting a kit the 5th Gen Civic Greddy kit for my Civic (its a 97). He told me that the downpipe wont fit and Id have to have one custom made, and that they arent using they ecu thing anymore they are using Regulators?!?!? I thought that the kit was pretty much bolt up and that all you have to do was splice the bluebox into the factory ECU. So will I need a custom downpipe? I didnt think I did.. I think he didnt have a clue what he was talking about. Can some one let me know in details about getting the 5th Gen Greddy kit to work on the 6th Gen Civic EX..

Thanks
