Exactly, yes I coulda mentioned that the exhaust isn't what makes it pop but can control the amount.
All cars have this programmed into their decel programming, but most cars DONT use a tube style, straight thru design muffler. Factory, you'll notice the truck doesn't do it audibly at all. Once you remove the cats it dosen't do it, removing the resonator doesn't do it. But once you slap your Magnajunk on there it starts a popping. Use of a chambered style muffler changes this dramatically. But if you take the muffler off about any car and replace it with a thrush, glasspack, bullitt, or magnaflow style straight thru design it'll have the decel popping. Catalytic converters do take alot of this popping away due to burning the leftover gas and catalyzing it. Even now with my Mac 3' chambered mufflers there is little popping at all. EVERY magnaflow,Dynomax bullit, or any straight thru design will amplify the popping 100 fold.
Imagine a ricer car that was quiet as all get out till rice boy got an extra $200 for a fart can to add on his car minus his muffler. BAM!!! You have instant popping and ESCPECIALLY decel popping these lil focker love.
For all you real redneck out there remember ( unless you still have the damn thing) the days of an 77' Chevy Silverado with a 350 and true dual 2" pipe and what muffler? You had the most poppinest cracklin', ride thru town in first gear, waking deaf people, ride of rides out there. I literally use to want to shove tennis balls in every redneck around's pipes to shut that tarded ass sounding trucks up.
