Had a resonator installed by midas. Exhaust sounds. Loud. Is this after market part the problem?

just prior to having resonator installed on a cold morning when turning the ignition I heard a puff sound which seemed to be at lower part ot engine around cat/converter area. Car then started ok. Have heard same a couple times after resonator installed

also have had a hissing crackling sound inside car when turning ignition

The resonator may be the reason for your car being loud. Have a pro listen to the hising/cracking sound as online here we would haveno idea other than a vacuum leak.
