So I spent all weekend taking the manifold, throttle body, headers, and flowmaster setup off my GTO so I can sell it this week and I sold everything but my Flowmaster Super 40s. I dont plan on modding this truck much with the acception of some engine management tweaks and probably put some pipes on it just to **** off my neighbors. But does anyone have specs on what the inlet and outlet sizes are for the 4.7L durango limited?

I wont get any gains from them obviously but I cant have all my neoighbors thinking they won now that my car doesnt wake everyone up in the morning...

I apologize for the stupid question but I am not familiar with this forum yet so I dont know where the best place would be to ask this.

 

You have a 2nd gen D right? I am pretty sure with your engine size it hasn't changed from the 1st gens. 3 inches all around.
