Most gearheads have probably already upgraded their muscle machines with a set of headers and a good dual exhaust system. After a few years, it's not uncommon for the mufflers to wear out (get crunched, rot out, or blow out the baffling), but what if the rest of the exhaust system is still in pretty decent shape? Such was the case with a '66 Chevy II Nova that frequents the Car Craft offices. Rather than install a completly new (and often costly) exhaust system, the goal was to just swap on a set of new aftermarket mufflers at home. Sure, the final look may not be as professional as what a muffler shop may do, but you'll save a few bucks and have pride in saying you did it yourself!
