If anyone can remember the bumblebee at the last two nsxpo's I have been running the dc header and exhaust,with and wo cats.The dc header are nice ,well done,my first go round was not so good.Back in 97 there werent too many H/E options.My first header had the o2 bolt location wrong and the bolt was aiming against the gas tank fire wall.Dc customer service was good and I got a revised one quickly.Just recently the exhaust blew a baffold(talk about bumblebee!) that was embarrising driving an nsx with a shot exhaust.I replaced it with taitec.Anyway the dc exhaust is as big as stock and is not much louder.With no cats though I thought it sounded great and had a unique tone different from all others.The quality of the exhaust was'nt as good as thier header,imo.The tips are single and are thick-walled ressenated tips the pollish tarnished slightly more than other exhausts I've seen.Hope this helped.
