ok so i currently paid off my credit card and wanna run it up again i have a 2002 gt i have 3.73 on it and its auto. i had 30 series flowmaster but currently have straight pipe due to the fact thats it sounds way louder. im thinking what should i buy first throttle body or intake or pullies or what i have looked at the tb n the 70 or 75 im lost what is better some say that 75 is over kill and if i was to get pullies what brand i no that if i get intake im going with kandn

get cold air, then a tb and plenum, an engine is a giant air pump so if you want it to perform well let it breath, pulleys are okay but i have always had bad luck with them, when i installed them on my car my headlights got dim and when i would step on the gas they would get brighter, it didnt perform to my expectations. if you want more power think more air and fuel, after those mods i would move onto cams, tune, heads, lower intake unless you buy a complete set the first time

That's what Underdrive pullies do. They underdrive everything except for the crank, releasing more power to go to the crank, and less power for everything else.

Longtubes and a midpipe.

Either that or max the card on some boost.
