hi, i am importing a 67 gto ho auto to australia and am thinking about buying a complete exhaust system to put in trunk before car ships, my exhaust manifolds are fine they will stay, i want a system that will give me the best performance and i do want to hear a nice v8 rumble too of course , but want to avoid any drone ...any suggestions on the best system out there....thanks

Stay with a 2 1/2 inch system, max diameter. One owner's ideal exhaust system is another man's nightmare. IMO, these cars sound just right with a stock system and a pair of old-style Walker or similar Turbo mufflers. No Flowmasters on anything I have to drive. Overly loud, droning/rumbling exhaust gets old fast on any car that's driven more than 5 miles a month.

:agree 2 1/2 mandrel bent pipes, I used summits kit they fit nice and the price was right straight duals no crossover all the way back to the bumper, swapped the cheap turbos for Dynamax 14" mufflers and it idles nice and low and growls when you get into it, no drone at low throttle relatively quiet for a 463.

here ya go for comparison
