S Smoke New Member Jun 8, 2012 #1 With Just the Headers fitted to the engine has any-body ever checked the Db levels?
adxx Member Jul 10, 2012 #2 what do you mean? Stock exh, straight pipe, no mufflers, no headers? What dB do you wanna know?
adxx Member Jul 12, 2012 #4 My 80mm exhaust produces about 105 dB @ 4000 RPM, so just headers should be above 110 dB, I think
