I found what I think is the best sounding and best performing exhaust setup. I tried having just the center muffler removed. Sounded like a Honda. You could hear and feel the 2 rear resonators/mufflers just vibrating. Removed 2 rear resonators/mufflers. So basically straight piped from cat back. Sounded like an even louder Honda. Just too open. Lost all low end power as well. I had a magna flow muffler installed with straight pipes back from that. Sounded way better but too loud and at high rpm the Honda sound came back. Finally I had a flowmaster 50 series delta flow installed. Also under the driver side just after the cat, there is a restriction point which is only about 1 inch diameter. Had that cut off and 2.25 inch installed in place. Now it sounds perfect. Sounds incredibly similar to a police version charger that I test drove to compare. Minimal interior drone, nice deep low rumble. And at high rpms the sound gets even better. And no Honda sound. Doesn't even sound like a v6. Feels alot faster. Only other modification to the car is an AFE cold air intake.
