This is the new YS header fitted to my Valiant. Much easier to fit and will solve the problem of the flange screws coming loose. A very good quality product and very neat. Fits the #821 Hatori muffler.
The Header is available in a 10mm and 20mm rise. The YS header weighs 3 grams less than the Hatori header. I will be fitting the 175cdi as soon as i get a chance.
