Im running a Power Vision with Fuel Motos map from Jamie for my setup which has been further tweaked with a bunch of tuning runs.....I dont think Im lean..
They had a problem before....not saying its on them either.. I could be running hot but I doubt it.

 

Over a year and 12000 miles, no discoloration on tips or muffler bodies

 

Well just to let everbody know Tyler at Rinehart is stepping up to the plate and they will warranty my endcaps after seeing the pictures. I was contacted today They said the discoloration is coming from the exhaust leaking out of the seams at the muffler body and the end cap. They are sending me new caps and said when I insatall them to put a bead of high temp Permatex on them. Makes me feel alot better as we know these exhausts for our bikes aint cheap and them only being a few weeks old was going to make it hard to swallow if I had to live with it.....so props out to Rinehart Racing!!!!

 

Heres a few pics of what Im talking about..

No fading on mine. I dealt with fading black anodizing on my boat motor and rail kit a couple of years ago so I took my stuff to a coating place. I was told that hard anodizing is better and doesn't fade, so I did that on my boat stuff.....no fading! If the Riney tips go purple, theyre getting hard anodized! I like the black!
