New MagnaFlow Exhaust
I just had a stainless MagnaFlow installed in my 05 Tahoe LT. Man it makes that 5.3 Vortec sound evil. Nice deep, throaty roar. I'd say it sounds better then the FlowMaster in my 98 Silverado and the Borla in my 96 Impala SS. Next mod will be a K&N cold air intake. Regardless of size or make, there is nothing like opening up an engine's intake/exhaust.
Sometimes there's justice and sometimes there's just us!
