Hi, Just purchased a 2010 Ultra. 6000 miles. All stock except the Bassani 3 1/2 slip on mufflers. The rt side muffler has turned gold in color. Is this a tune problem or cheap muffler issue? Thanks

 

Most likely a tune problem! Running to lean.

 

It is also because the stock head pipe has the catalyst in it most all bikes I see come thru the shop with slipons and the stock head pipe all have the right muffler blued or gold because the heat that cat puts out is right infront of the right muffler. A tune will help some but getting rid of the cat and tuning is the best way
