This is a bit of a non LS question...
On a production based car, but with a flat bottom, front splitter, with a center channel, side boards and then a decent rear diffuser with strats, that start just in front of the rear diff... also a rear wing that lays back about 8 inches or so from body work, and at roof line height.
When plumbing the center exit exhaust into the diffuser, is it better to have it pointed straight back, horizontal or to angle it so the exhaust flow follows the shape of the diffuser?
My imagination makes me think that if it's angled up, not only wil it help pull more air to expansion (the diffusers role) but then if I can get the flow right, the exhaust at load will push air up to assist in extra flow along the bottom side of the wing, increasing its effect with out drag...
Or am I way wrong here...
