Front end vibration/resonance

2022m3x · 02-01-2023, 06:53 PM

Having resonance/vibration and/or “rumbly” acceleration at low rpm. It happens on and off at around 1200-2000 rpm especially after doing some hard acceleration. Did recently install a midpipe that removes secondary cats and first resonator. Anyone else with exhaust mods experience similar issue? Resolutions?

Check the clearance on your brace to midpipe.
