Okay, here's the deal, dropping in new 350 shortly to replace old 305. Current engine has y-pipe, single cat, single muffler, dual exhaust. I am considering going with true duals, but decent free-flowing cats cost $120 each. So, not including labor and pipe hardware, true duals would run me around $360. Single free flowing cat, single flowmaster, dual exhaust would run almost half that, $200. Is it worth the extra to go with true duals? Really?
