Found a loose clamp after checking the exhaust, but still getting vibration while idling in drive. Could motor mounts possibly cause vibration after installing long tube headers? Car doesn't have vibration while idling in park though. Engine RPM seems to be a factor too. I noticed that vibration is worse at the lower the engine RPM, hence why the vibration is worse while idling in drive vs park.
