Swapped my Flowmaster 40 series to a Flowmaster Delta 50 series. What a HUGE difference! After I put on my longtube headers, the truck sounded ratty and had a ping to it @ 3,000 rpm. After the swap, the truck is way deeper, smoother and still has the growl @ 3,000 but no ping anymore.

The inside cab noise is about half. Still hear the truck, but no more yelling when driving down the highway!

Also swapped the Superchips out with the SCT Hemifever 93 Tune. The hell with Superchips! The SCT has awoken the BEAST!!
