do i need a new intake manifold, something other than the stock or at least new injectors to reach full potential? if so could i please get some links for injectors or manifolds?? thanks

 

No, you wouldn't need a different intake manifold or larger injectors.

 

It will be very, very loud.

 

not really i had this set up on my old fc, for the love of god get a good cat in the system or it will be crazy loud.
As for the porting i had a basic street port and i didn't really notice a difference, this time around instead of spending the money on the port, i will be using the money to send out my injectors for cleaning and balancing, oh and i also will be getting the pineapple sleeves put in and getting a racing beat flywheel.

 

The benefits of the true dual system are negated with the installation of a cat.
