Oh okay. Which company makes the quietest universal muffler? If I can't get a cat-back, I would probably be custom my own 2.25" mandrel bent pipe with aftermarket resonator but I don't know which muffler is the quietest one.
Basically I just want an exhaust system that has nice low deep tone, nothing loud. The A'PEXi WS sounds great. I've heard the sound of the A'PEXi WS on my friend's Honda Accord V6 & I love the way it sound. It's louder than stock but pretty close to it.
The RS*R Ex-Mag is a nice exhaust but I don't think they make one for Camry.
