I heard the "Famous blower noise" for the first time after I installed the 6lb lower pully and I was told it was due to turbulance in the blower casing. Either it went away or I got used to it, but I cut off the rear cats yesterday and when I started the truck this morning the noise is back x10. I will be changing the coupler pretty soon, but would a loss of backpressure cause the marble sound to increase?
Thanks!!!!!
