I'm getting a Buddy-Club Pro-Spec exhaust on my DC5R and Toda Headers. When you've heard that combination when it idles, turns heads. Moderately loud and fits the Type-S. If you want a low-base type or exhaust feeling then go with Spoon if not, and your into outrageously loud go for Buddy-Club Spec. II (you literaly go def. no joke its ear numbing and VTEC sounds like a jet roaring past). Power gains are all about the same usually 5% more power gain with spoon, mugen, toda, buddy-club etc. Spec II has the best gains as it comprimises noise pollution for a nice 7% power gain. I've done research into exhausts and witnessed many DC5s coming out of my friend's performance work-shop. Fujitsubo is ok too as the others said. You'll find Spec. II to be the cheapest, the loudest and the best power gains (as it is a straight pipe cat-back).
