[QUOTE="bigrpowr, post: 449706, member: 806"] What are you talking about ? This about data , not cheer leading out purchases and padding ourselves on the back for making up pipes. If size is the issue according to you, why is the outlet 2.5" ? Let the professionals do the test then we'll know more. Ps who says that there is it dead head'ing in the manifold itself ? Who knows?? My truck could be a fluke, never know. Please grace us with data not observation. There was a truck at fuel fest that has dyno'd over 600 , and should be at least at 600 all day long, he had them on and the truck made 540. [/QUOTE]
