hey my old muffler was rattling and it turns out the metal thingies inside the muffler has rusted off and being a really large rattle, bottom line, i need a new muffler,

my friend has a relatively new dynomax he got from work (free). is that a good choice? i'm not a big muffler fart sound guy. as i found out today cause my friend broke off the rusting tip coming off the muffler

whats the best muffler being top on performance and low on sound?

thanks in advance.
