mufflers

i got a 92 ford f150 shortbed as my daily driver and i had a 3 inch pipe into a 3 inch cherry bomb extreme and out a 3 inch exit only one pipe and i showed up a chevy with dual exhaust had the most aweful high pitched whine id ever heard and chevys always run flowmasters along with the mustang bunch however while they sound good for city cruising and avoiding cops i love my cherry bomb extreme one pipe sounds like two i have a 78 dodge macho power wagon that may have a 360 with a mild crane cam and worked iron heads a 4 bbl carb full length headers and dual 3 inch exhaust with the cherry bomb extremes unless i find a decent duster then that will get the 360 and prolly the race bullets
