no point in having a decat if running with a stock system tbh as its pretty restrictive, the decat can be fitted onto the std manifold ok , what was mentioned was to have your original manifold modded to remove the APS to get the most out of your exhausts air flow but you dont have to, and run with a power/superchip 164 ish is a easy target
