The exhuast system had already been previously replaced, its already rotting/rusting though, crap cheap exhuast places, i plan to replace the rear cat up front with a carsound and the muffler with maybe a magnaflow or something and all pipes to stainless so ill get some years left out of it. The truck is in awesome overall condition and i dont use it too much, only for my lawn business in the summer really. It LOOKs like it has 2.5" pipe, am i correct? i want to buy the right parts before i rip it off and start rewelding, i have brakets that broke/rusted out, pipes almost rusted through and mufflers rusted out in the rear, almost leaking.thanks!
