The Flowmasters come painted black, so I'm assuming it's some sort of added rust protectant. I also added another few coats of VHT FlameProof paint.
I'm old school and absolutely love the growl of a V8 (nothing like it), so my plan is to keep the car for about 3 years and trade it in for an SS 1LE.
