with my friends 4 door lx we are trying to figure out everything ahead of time before the swap just wonder what people have used for an exhaust manifold or if they upgraded from stock h22a to a header what they have used since we have been told the regular h22a manifold wont bolt up directly, also heard that the h22a SH manifold has a flange on it and will bolt up. if people have done this swap which i am sure they have wondering what they have done

 

On my 97 swap i used a crappy *** DC header for my H22 adn then cut the down pipe accordingly and used the flange off of my old DC accord header and bolted it to the accord cat.

Accordhybrid

 

i also used a shitty header, but it works...........then cut the cat off and had a test pipe put on
