cobra 2001 increasing horsepower

[cobra0311]

I bought a 2001 cobra mustang and I bought MAC long tube headers, MAC prochamber pipe, and flomaster 40 series catback exhaust I was wondering what else I should buy to give me some horsepower?

Air Intake, Underdrive pulleys, Throttle Body and Mass air, a chip.

Not sure if you want to go the supercharger route but that is an option.

Gears would also be a good choice. Preferably 4:10's.

hope you don't drive in traffic ,but might not be so bad since its a cobra.

Make sure you get a prof. to do the work.
