I've got the replica narrow style , good gains, can feel it up top. Would love a real big tube version though

If looking for low --> mid, i know 4-2-1 are good but which brand is best?

All the top headers seem to be 4-1 design, maybe 5Zigen 4-2-1?

off the shelf best header is toda by far, great quality , great gains

thank's for your advice. i found a set of big tubed 4-2,2-1's on ebay. for $300-ONO, but gonna offer $250. and $120 shipping.('see what happen's). thinking of getting 2 header's one for my da/b20v and the other for my G/F's dc/b20v-jrsc. would it be a must to re-tune the s200 in the dc/b20v-jrsc after installing these pipe's? would it mess with the A/F ratio? considering there'll be less back pressure?
