#261365 hi all,

need help on what cat to use on my hatch. in the process of changing out my D15 twin carb motor in my EG4 for a B16A out of a JDM EG6 and need to know what and where to grab a "plug 'n' play" high flow cat to suit a 2.25 cat back system and type R headers. i have heard that sohc cats are different to dohc one's, is this true? and if so, how?

thanks for any help guys

what are you doing with the dual carb setup? i would be interested in the cylinder head,ECU, and the Intake manifold with carbs. Please PM me.
