Yes. I drive a 97 4runner and i put a 40 series flowmaster on it. It sounds good, but its not a v8 sound like everyone wants. it kind of sounds like a weedeater with a straight pipe. idk how to explain it. but it has increased my mileage by like, 2 mpg and it feels faster. partially because of the sound but it obviously accelerates faster too.

The 1986 4Runner could be losing mileage for several reasons. The engine could need a tune up. The fuel filter could need changing. The engine could have high mileage, causing lower fuel economy. Or the transmission could be slipping slightly.
