I am a little confused when you say you wouldn't need exhaust manifolds with the NW downpipes. Are you talking headers here? In a V8 you can use the same down pipes but you have to have the top 4 inches or so redone to match the V8 exhaust manifold which while very close to the V6 is angled slightly different. the mechanical work is pretty straight forward but don't underestimate how much work is involved. It is a lot of work!! Also without Rudy's help it will never start!

I have the system to do the programing and there was no way I was going to figure it out. Trust me when I tell you that the programming is right up there with brain surgery and rocket science if not harder. Think of it as rocket science in German. If you can't speak German it is harder than rocket science. Besides Rudy, there is only one other guy in the world that can make your engine start and has had his fun and will not do another one, and unless you want to really be yelled at or have way more money than what Rudy charges, don't even ask him.
