R56 Resonator vs Cat
Resonator vs Cat
About a year ago I installed a custom exhaust. Deleted the resonator and installed a super 10 flow master with a tip. I love the tone and the volume but the drone is starting to get to me. Right around 3500 RPM. So I'm thinking about installing a resonator again. Has anyone tried vibrant performance resonators? Has a anyone ever replaced the second cat with a resonator?
