yea, get someone to patch those holes up. and no, cutouts don't have those noises. cutouts funnel the airflow out, with holes in the side of straight pipe its just gonna hiss its way out like any other pressurized leak. for $35 bucks cutouts aren't expensive, to get one installed isn't expensive. these cars, while they aren't ferrari's, don't like it when they aren't treated right. hacking up your y-pipe included.

Just one question.. What the hell were you thinking? You create an exhaust leak and then wonder what is wrong?

Ok.. yea.. just have that hole patched, or get a cutout to replace that damaged section.
