looking at the pictures, aftermarket parts,, you have a needewings single intake,,,,,a small SC pulley maybe 65mm or 62mm , with belt rap kit , , and best of all needswings intake manifolds, go to NeedsWings.com and check out what all this cost, close to $3000.00
the exhaust manifolds are stock. i don;t think you have a catch can, left side of engine near shock tower.
with all these goodies i would think you have a ecu upgrade, it does not make sense to have those performance upgrades and not have the ecu and maybe the tcu upgraded. jim
