What are *restrictive* parts on the 4.6?

I can tell a million things about what restrictives about TPI's, LT1's and LS1's. What are restrictive about the 4.6's? Exhaust? Manifolds? Plenum? TB? Intake?

eh. restrictive? hmmm not too much, a full aftermarket exhaust and intake will free it up a bit, but im not sure anything is too restrictive besides the speed limit signs.

One of the most restictive things are those stupid stock manifolds. Get some LTs.

Most restrictive part would have to be the motor itself..

The stock manifolds arent that restrictive. THat's why shorty headers are almost worthless unless your very heavily modded. The midpipe is probably one of the most restrictive parts.
