Which Mufflers are best for Fuel economy
I know lots of factory mufflers are pretty restrictive which can affect fuel economy.
I've never seen any studies on these but I was figuring, though i don't like magnaflow or corsa exhaust ( because i prefer the chambered sound of flowmaster). When you really think about it magnaflow and corsa would probably be the most efficient aftermarket mufflers because they are straight through desings...
Flowmaster probably is betttrer than most stock mufflers but not the most efficient.
And i know cherry bombs and glasspacks are probably the worst because they are veeery restrictive
Anyone know any fuel economy differences between mufflers?
