    For the cost of a true dual exhaust, it will be a LONG time before you make up the cost difference. The tacomas I've seen with true duals had negligable (if any) improved mpg. Believe it or not, the factory exhaust is fairly decent flowing.

    i have a single in and dual out magnaflow muffler and i didnt notice any difference at all in the mpg, it was a decent difference when i paired it with the deck plate mod. but exaust alone is not going to make any noticeable difference other than sound. unless you do a full exaust with headers and all

    X2. I have actually seen better gains with a single exhaust than a dual, on most NA engines.
