Default Exhaust popping on acceleration.

I know you have seen/heard this. Old worn out truck that has duals out the back, beat up, redneck sticker on the back, and the exhaust pops when they accelerate. ***It sounds like *******


My exhaust is set up as follows. PS longtubes reduced down to 2.5" running through gutted cats and on through a Dynomax Ultra Flo X muffler, then runs over the axle and out the back.
WHAT CAN I DO BESIDES CHANGE THE MUFFLER, TO GET RID OF THIS PROBLEM?

It sounds like hammered dogshit.

how about adding some magnaflow resonators like kysilverado did. he said it mellowed out the drone of his exhaust, matbe he''ll chime in. Ive heard 2'' exhaust cackle but not sure why 2.5'' is doing it.

throw in two dynomax racing bullets and your problem will be solved and they are only 50 bucks for a pair

Because i need to look somewhat legal. Do you think the dynomax bullets will stop the popping?
