Hey guys, maybe this will help...
Both BDE Ti muffler end caps behave like Stainless (and must be) and the mid-pipe (that we polish free with an exhaust purchase) IS Stainless. The end caps arrive from Hindle already polished. The rolled muffler shell that VelTune polishes is Titanium. I have never seen or heard of our polished Titanium work discoloring!!! I ran our first polished Ti muffler for about a year under all kinds of riding conditions and there is still no discoloration of the Titanium shell.
Stainless, however, will discolor with sufficient heat-time (the end caps and mid-pipe). These Stainless parts require periodic hand polishing (a clean rag and a good metal polish like Wenol or Mother's Billet Polish) to keep them bright and shiney.
Here is my routine advice to VelTune customers for polished BDE exhaust maintenance, ver-batim:
<span style='color:red'><span style='font-size:9pt;line-height:100%'>When the polished Titanium muffler gets dirty from routine riding, I recommend that customers gently wash it with a SOFT, CLEAN cloth using clean, soapy water. After rinsing, any water stains should be hand-buffed with a clean, soft bath towel. ***I'm talking about bath towels straight out of the washer/dryer... THAT clean to avoid even a particle of hard sand or grit that could scratch the polished surface.***
The polished muffler end caps and mid-pipe are stainless steel. Both of these can be touched-up with your favorite metal polish using a CLEAN rag as needed to restore their shine. If the polished mid-pipe starts to turn colors from high heat, just touch it up by hand. The shine can be maintained indefinitely if hand polished with regularity.</span></span>[/QUOTE]
The key to keeping polished stainless looking good is to hand-polish it when the FIRST SYMPTOMS OF DISCOLORATION APPEAR. If you let it go for long, the discoloration takes a deeper "set" and is more difficult to polish out by hand. In severe cases, the part may need light machine buffing again.
