Its about 4600 feet above sea level here and Tucson usually has an awful DA. Its one of the slowest tracks out there but when I get there ill be sure to post some numbers. And its got factory manifolds installed the same way as they came from the factory. I did all the piping from there up to the turbo and 3.5" downpipe to dual 3.5" exhaust. All the hot side was done after the manifolds in stainless steel and the cold side is all aluminum TIG welded together
