Hey shonnv, I just bought an apexi ws2 for my 6th gen accord, I gotta say, it's sweet. I used to have the Greddy Evo it was too deep. I did a lot of research and finally bought the apexi ws2. I spent $ on the exhaust twice so think twice before you buy your exhaust.
The apexi looks very good, has good clearance, and sounds just great. It's a little louder than stock, and has a low grumble sound, like a nissan z or g35 coupe. It does not gain any HP but it makes you feel like your car has more power. PS: when the catback is brandnew, it sounds very quiet, very close to stock. After two weeks, it's broken in and the sound is louder and deeper. I have some pics but I left my camera at work. I'll try to post them tomorrow.
