Hi,Selling Magic Wonder Gel it works on stainless steel header and full system.I bought for own use balance few bottle left. As a biker I totally can understand the feel of having a stain mostly cause by heat generated and environment & etc.and is very hard to remove the stain. Here is the product I like to introduce to all Magic wonder Gel Magic gel was developed with a special formulation & concentrated gel to remove hard stubborn stain from plated surfaces. Powerful cleaning gel to clean and shine without much effort. It bring the exhaust header back to look New & Shine again. What you see from the pic is my actual 20 Mth old bike and a 10 years old Super 4 spec 3 first time using it and it look new and shinning as well. Give your $25 a worth try unless you want to opt for ceramic coating that will cost ard $300. Which I have done it on my previous bike. So hurry don't wait buy now I will provide you the brush and latex gloves..
