They sound GrrrRREAT! La Franconi slash backs fit and work well !
Get the police mufflers (Lafranconi Frankfurters).
Then remove the baffles (held in by screws).
Sound and look great but aren't too loud, and they bolt on.
I've got the La Franconi slash backs - where are these screws and baffles to remove? Will removing them hurt engine performance by lowering exhaust resistance?
