[QUOTE="ytradio, post: 432439, member: 19779"] An exhaust leak on a cold engine is pretty common. I personally would start by re torquing the header bolts, sounds like they were not re tightened or as we would say in heavy industry “hot bolted”. If you could re tighten while the engine is still hot all the better. Another good place to look is the header to exhaust pipe connection. This may be easier to hot bolt. Header flanges are usually thinner and harder to get a good seal than the beefier cast iron manifolds. [/QUOTE]
