What Performance/Economy part next?

Do aftermarket mufflers really help in the performance/economy of the truck?



I know I don't want an obnoxious/loud exhaust. My factory exhaust is still in good shape, but if I can gain a true . 5 - 1mpg better in a daily driving scenario, I would be tempted to get one.



I will probably be doing tires later this fall.



I've read about MBRP, Aeroturbine and a few others.



Thanks for any/all opinions.



Later,



Bob

Yes. You want to minimize the restriction in the exhaust. In general, minimizing intake and exhaust losses (which means minimizing pumping losses) will make the engine more efficient.

but if I can gain a true . 5 - 1mpg better in a daily driving scenario, I would be tempted to get one.

I doubt you'll see that much gain in fuel economy, on average.
