I have a 2016 sierra 5.3 with a flowmaster super 10 and am getting awful fuel mileage with it and I'm driving easy (9 mpg) was thinking of going to a straight through muffler like dynomax bullet or bullet mini just wondering what one would be as loud as the super 10 because I like how aggressive it is. Any help appreciated thanks!

which one are you using.... no flapper or res correcct?..... i think our stock pipe on the 5.3 before the muffler is 2 1/2?...... so 2 1/2 - 3' out...

i have the regular bullet, not mini. I don't have the flapper anymore and I have the 6.2 now which STOCK is 3.5" up to the muffler then I believe is 2.5 at the flapper then after the resonator is 3"
