Should have more. But a tune may get better results for the $$. D2 responds well to enhancements though, so not sure. Suggest you keep the muffler if possible until after you try header, only in that many have posted there surprise in how loud the exhaust gets. Got a pic of your ram air setup?
Edit: sorry! you said D2. You will prob want smaller primaries. That would be the OBX header. The FSWERKS header will prob kill you low end torque as it is for the D2.3.
