the smaller the motor and the larger the percent of power available used the more important the muffler and pipe flow becomes, also the less aerodynamic a vehicle stands to reason your using more power per mph thus need more flow also. many high perf mufflers are very restrictive to air but not the noise, look inside a cherry bomb muffler and see the small pipe size , yet not very quiet. noise reduction and flow reduction not the same thing.

anither point is the Ranger I own the 88 has a way too small pipe size than most newer, read , designed for economy .have so there is such a thing as losing FE with a too small pipe size for a high drag vehicle where your using maybe half or more th eavailable power, mine is 88 HP when new. now maybe 70 , under powered cars and truckw will benefit most . I would definitely look down th ebarrel of the new muffler and compare it to a factory original, big difference I'll bet, my replacement auto zone muffler was just too small I figure, so i did notice a decrease in FE
