need help with some plans....

As of rite now i got AEM cold air, NGK 8mm wires, vortek muffler and thats all the motor work done to my car. In june and july im goin do the mini-me conversion and get the AEM fuel rail and fuel pressure regulator. Im goin to try to get the APEX'i V-AFC but im not sure if this summer or winter. And i think im goin to get a throttle body from a b18a but i dont think it will bolt-on. Over the winter im puttin my car up and takin out the motor and rebuilding it. i was thinkin about buyin the GReddy SP2 cat-back exhaust this winter. should i spend the $500 on the exhaust or get a new intake manifold and some other mods???

do nothin your car is slow..... na but for real you should know better then to pay $500 for an exhaust ...... do a all custom exhaust thats what im doin...... thats just my take....
