do fmax downpipes run 2.5 inches thru the whole thing, does any part of it taper to a smaller diameter to fit with oem catalytic converters? or do you just have to depend on the flanges matching up? should the oem cat be smaller in diameter than 2.5 ?

planning for the fmax t3/t04b turbonetics for accord 98

yeah, it'll match right up to your stock exhaust. its 2.5" and then at the very end it tapers down to like 2" to match your stock cat, and as long as you get the kit for your car it should match right up.
