MUFFLER OPINIONS

Hi Wayne, the "HEMI" designation/size came from their dimensions and that they were used on the HEMI powered B bodies as well as the 383 and 440 versions. And the Little Red truck. They are aorund 20" long, about 4.25 by 10.25" ovals and had offset inlet, center outlet 2.25" inlet and outlet bushings. They are three pass mufflers and the closest sound I've heard to them are the ones Waldren sells although theirs are a little cracklier and more hollo sounding. Their Imposters are a bit louder and more rumbly. The 17748 SuperTurbo matches the sound pretty closely and will pass more air and exhaust gas through them too.
