Pypes High-flow catalytic converters.
Ok one of my catalytic converters blew out my tail pipes so I am forced to get a new one. Now im looking into pypes high flow ceramic catalytic converters to replace both of my stock cats. Will these new high flows need a tune for my stang to run normal? Or would it need a tune? If it does ima have to pay alot of money for a used one off another mustang.
