Please dont remove the resonator. It helps kill off a bunch of the rasp, and quite a bit of the drone our cars inherently have. If it's rotted out, do as scotty said, and just replace it with a glass-pack (cherry bomb, thrush, etc) with the longest, fattest one you can get.
You wont gain any performance from removing it. Better to save that money for the headers. You'll get a noticeable sound difference from just the headers.
I agree... I removed mine on the gtp and regretted it instantly...
Sounded like ****...
