i have a contact for having exhausts treated with coatings simlar to those of zircotec is anyone intrested in it ? it will be a lot cheaper as well dont ask me how much yet but if you are intrested pm me first , by the way this stuff has been used in F1 its to reduce heat in engine bay and a long the length of the exhaust as soon as i have more tec info i will post it the idea is to produce more horse power and a better running engine
