I think you are on the right path with the pulley,software and exhaust upgrade. As far as the exhaust goes you cant go wrong with ours... it replaces the restrictive factory piping and is completely bolt on.

For those of you looking for High Flow Cat options. They are available and we have began shipping. Visit out X Pipe thread for more details.
