It sure does look nice. But you should realize that stainless with also discolor with heat cycles Jimmy. Plated steel is not the only metal to succumb to heat.
Stainless is a great metal choice for motorcycle exhaust because of its corrosion resistance, but it is more brittle and will suffer from the heat cycles more than a mild steel. Ultimately, it will crack sooner than mild steel, but mild steel will corrode much sooner than stainless. I understand the Hindle system uses a much thinner walled tubing than others, so its durability will be interesting to note. Not suggesting for a moment thats its not a First Class product, just making an observation.
I'm fortunate that all my 5xxs use a perfectly fitting, top class stainless 4:1 from another so my need to explore the Hindle isn't there. But for 650 guys, it looks to be the cats pajamas.
