+1 on JBA quality- had a set on my 5th gen 3.6 LLT that was supercharged and put out tremendous heat. The headers never blinked- no color change (ceramic coated) or any adverse effect to this day.
That exhaust ran so hot after a bad mod at an exhaust shop, I thought I could drive the 1.5 miles home with the exhaust tips touching the plastic at the rear and then fix it- it melted the plastic before I got home. But the JBA's were never fazed.
