My first post, but anyways, does anyone know what the part number would be for just the resonator/center muffler for the 98-04 Seville Corsa exhaust system? if they even sell it separately. I found a deal on just the rear y with mufflers and tips and can bend my own center pipe for it as long as I can get the resonator. Or does anyone here have that system with the resonator replaced with straight pipe? How does it sound?
