    Welcome! Unfortunately there aren't a lot of performance mods for these cars. The intake is a good start. A few other mods you can look at is an isolator and a catch can. You can get those at

    Also, you can try and look for an exhaust from a CTS-V. They make a nice upgrade and great sound. Or, just search around on here and there are lots of threads on custom exhausts. The intake and the isolator and exhaust will get you near 300hp. That is a out it for power mods. You can get upgraded brakes, suspension, sway bars etc. just do some searching on here and you will find tons of info.
