My old OBX 2" muffler looked and sounded awesome, but it was just too loud for me to handle. So installed an OEM '01 Civic muffler. I've been meaning to post up about it earlier, but never got around to it. It still sounds sport, since the rest of my exhaust tubing, cat and resonator are still 2 pieces, but it's quieted right down. I know it seems counter productive to you, since I have some pretty lofty goals with this car, but don't worry, I'm installing one of these this spring...
