I got my apexi WS about a month ago, and I love it. Not some pos rice sound.

I would have to agree with Born To Lose's description, but I love how I can hear the engine/intake over the exhaust when i gun it. A exhaust should never over take the sound of the motor when u push it to the floor in my opinion and thats why the WS, Rs-R are great Cat backs. And they both look great on a integ.
