Hey man although this was in the making for a couple weeks I didn’t know it was going to end up with me, so I had to make arrangements to jet out to Maine like the day before… As for the M50 manifold, yeah I hear it gives nice gains for like $100. What’s the best install kit? And doesn’t it make the car fail inspection since it’s an OBDI part?

Highly recommended. Sacrifice a little low end torque for lots of top end hp. No emissions changes.
