Hey Jedi.
Jason touched on it briefly in a previous reply, but he's absolutely correct. The torque dip is 100% livable now with the headers. The axleback/downpipe smoothed it out a bit more, and made me rage at it a little less, but the headers... the headers made me pretty much not care about the torque dip anymore. Yeah it's still there, but- the car has as much torque in the dip as it used to have at the top end now (with all the other exhaust components on it). So the whole car feels faster, and that torque dip feels stronger by far. Case in point, on the handling oval video that I posted earlier, I was braking down to around 3-3.5k and wringing it out to around 6.5k at the end of the straights. I basically was living in the core of the torque curve that whole video. It still felt fun as hell, and accelerated well- not like in stock form AT ALL. I was able to break it loose while in the torque valley easily. (yes, I know I was in the rain.

The header, for sure. If someone else made power with the mid pipe, I'm confused about that. Nameless has dyno'd with and without the midpipe on two seperate occasions now and gained zero power, and it just added a ton of buzzy rasp and drone.
Also, note for everyone: Go change your page view settings. If this is page 13 for you, go make it 50 posts per page or something. much easier to view the forums that way.
edit: Jason, when are you going to start selling the catted headers to customers? I feel like that header design is complete for people that want a catted header, the only issue is adding a resonator to the downpipe. But maybe people want to buy the header now and get the downpipe once the resonator issues are all figgered out?
Or a header/axleback combo for now. That seems like a legit way to make some good power incrementally while waiting for the downpipe.
