TB_205GTI 1 Posted March 8, 2006 I have two stainless steel exhaust manifolds for my car. The one has been fitted to a TU5JP4 1860ccm properly remapped, the other one I have on my car (tu5J4 1860 - not remapped yet). The first one is bluish, and mine is almost purple.. Can you tell anything about the mixture from the color of the manifold? Share this post Link to post Share on other sites
RobMGti 0 Posted March 8, 2006 I wouldnt think you would be able to? I mean if its glowing red you know there is something wrong but i doubt it will change colour just because of a inaccurate mixture Share this post Link to post Share on other sites
hengti 2 Posted March 8, 2006 You can't tell state of tune from mani colour - just check your plugs ss manis go all sorts of horrible colours once they've been heated up a few times Share this post Link to post Share on other sites
