Okay so I'll run through the current setup, calspped long tubes with 3" ory, 3" bullet after the y into 3.5" piping to a Aero turbine muffler, non resonated, to 4" tailpipe over the axle. The truck has always been this loud but now with 4.56 gears and a 2500 stall converter its unbearable when accelerating. I love how it sounds now, just would like suggestions for a larger/quieter straight through design muffler. Don't want a magnaflow, not a fan of their sound. I know some of you guys have similar setups, looking for some help.
