The DX manifold fits just fine, however this car came with a DX manifold along with 2" to 2.5" piping all the way back. Going back to stock I noticed a gain in low end torque, which I feel this car needs to be drivable around town. I gained 3-4 MPG. The gains are honestly not fully realized yet because I haven't even gone through a full tank of gas. My commutes are usually 10 miles max each way between work and the places I frequently go, so it takes almost a month to deplete a tank for me.

I'm also certain too, that the oxygen sensor placement on the DX manifold as opposed to the VX would affect exhaust readings, or certainly not allow it to get as hot as it should. The VX allows the oxygen sensor to sit closer to where the manifold meets with the head.
