Mod upgrade ?
 

I have a 2000 V6 auto, it has a cai (off brand) and what looks like 2 1/4 exhaust with flowmaster mufflers. I want to put the windstar intake and new cai, 65 mm or 70 mm throttle body and upgrade the exhaust. It has a exhaust leak on the passenger side ( either the manifold itself or gasket not sure). What brand cai, throttle body and size exhaust and muffler or any other upgrades will bring the car alive?

I think rear gears would be about the best bang for the bucks. I wouldn't do anything else after that.

Look through this thread. Less of different options for give the v6 more power and a couple write ups on the windstar intake swap.

Thanks!!
