Ok so Ive had my exhaust system for long time now, and I have been having this rattle in the "resonator" I know it the resonator because, I put my car on the lift and starting banging on it with my hand. It rattles at idle and at stop, I not sure I have a warranty still on it so I called and they told me that I need to mail them the resonator in for looking to see if there dmg to it on my end!!!!! yeah I rubbed sometimes never banged the ground, but anyway back to my question lol, what are some of my options can I just get rid of it and replace it with a pipe?? anyone else had this problem, FYI i have NOOO money!!! =P
