Again.. I will ask what is your back pressure... we still dont know crap yet.. if you can say what your REAL back pressure is we would have a clue to what the flow of the system is.. everyone wants to throw out HP numbers but if system X is this much back pressure and system Y is this much it will say A LOT.. I measure mine so I do have a clue to what it is.. a simple gauge hook up will tell you EDIT And state at what RPM
Never measured and my math on my dart has been bigger heads, cams comp etc, like a bigger exhaust but it would be interesting to test some time but still would change it unless it WAS a restriction............
