would i ever need to upgrade my exhaust manifold from stock??? i have a the big 16g with cai and mbc i plan on upgrading to the fmic and bigger injectors and fuel pump and all the other lil things. any opinions would be great thanks aton

 

It wouldn't hurt you to port your stock manifold or go with an Evo3 manifold, but you're fine with the stock manifold.

 

I agree with silver, porting is a good idea. It will help with spool-up alittle bit

 

exhaust manifold and porting won't help you a GREAT deal but every little bit helps... nickles and dimes with horsepower do add up after a while. i'd go w/ the suporting mods to the E316G first and then start "nit-picking".
