Jet hot warranty

I had 3 sets done , 1• I sold the car w/in the first yr & were fine - 2 • I sold the headers before using ,bc I had back surgery and needed money(yeah, I took a beating $$) - LOL 3 • car sat for yrs (20+) after a piston cracked in less than 1 mile, engine had been sitting in a garage, it turned over but I quickly found the rings were locked in the grooves, all the coating peeled off that set, just sitting around ! 1 out of the 3 sets I can make an opinion - I loved the idea , brand new Hedman pipes coated inside/out - Ceramic Coating I my thinking - maybe nieve but thought would hold up laying under water , nothing is perfect I know , man, they looked fantastic when I got them out of that box - I wish you the best -
