Someone previously posted the horsepower/torque/dB changes from several axle-back muffler packs, as tested by MM&FF. Does anyone have that info? I can't locate it.
Also, most of the changes resulted in lost average HP/torque, but gains in peak HP/torque...nothing huge either way. Wouldn't a reduction in averages result in slower ET's, theoretically, despite the gain in peak numbers?
