Not long after I got mine I went to a muffler shop. I had them remove the huge anchor and save the chrome tips. Then he made a suggestion. We put on a Y-pipe and two resonators backwards, then the factory tips. I tried it first with both resonators in the normal direction, then one reversed, then both. Has a nice mellow sound, not the fart can sound. Just loud enough to hear it but not at all annoying on the freeway. Most of the sounds comes in between 2-3000 RPM.
Once you take off the factory muffler, look inside the inlet. They actually have the inlet on the side of the muffler case (huh???), and then it goes in and hits a deflector that makes it go both left and right. Doesn't seem too intelligent to bring it in on the weak skin instead of the stronger end caps, or to have it immediately run into a "wall" that forces it to turn 90 degrees in a short distance.
My new exhaust (over a year old now) weighs less and flows better (I'll bet), plus now I can hear the car when it's idling. I couldn't hear it before.
