lol wont see over 200rwkw r u serious?? full exhaust, cooler 14psi and advance ur timing lyk ive done and u will see over 200rwkw. mines pushing 209.7rwkw on 14psi loves every moment of it. call up any performance shop ask them wat power u want they will tell u wat u need. dont listen 2 cat back exhausts with standard cooler owners telling u what to do. my 2cents. Good day!!
