    Did you also delete the resonators? Sounds good

    I didn't, but I don't think they're stock

    Oh wait, I might be confused... We cut off those huge tumor-looking things near the back of the car. Are those mufflers or resonators?

    Here's a couple pictures

    Oh geez, okay that's what we took out....

    I thought people said don't take out the resonators or it'll sound like shit, but god do I love the way this thing sounds... I hardly use my brakes now because I don't want to miss out on the sound I get from downshifting.

    If I'm not mistaken, I've gained some low-end torque, and lost a little at the high end.

    I deleted the resonators and swapped out the stock mufflers on my V6. Made a huge difference.

    I did a resonator delete which woke my 2010 RT up immensely. Because the PO had done a lot of work on the intake and added long tube headers but left the stock exhaust it seemed to restrict flow through the system. Once the resonators were removed I could feel better response at the pedal....and the sound is awesome.
