after a year and a half of having my MG31 deafen me while under trucks on trans bolts i got my dealer to give me a muffler kit(handed it to me out of a new box and said take it...nice guy) and i installed it...much quieter now and my ears don't ring anymore
anyway, the reason why i took so long to get the muff is cuz i've heard from other guys at work and read on here that it reduces the output...i ain't put it to the test yet, so i'm curious if anyone here can answer me either way...
ps, if you don't have a 3/8 impact yet and want the best in the world, get the 31 or 325...damn thing will loosen 1 1/4 crank bolts...and they're as light as a feather
