A WAMS "tune" is the ONLY tune out there for these cars that improve your engines performance by about [email protected]
There are no "chips".
The custom CRAB intakes made by Lampoon are the way to go. The WAMS tune is designed to be used with the CRABS intake system. Easy cheasy to install.
Go to G6performance.com and search "WAMS". You should find a thread their with tons of info and a way to contact the guy who tunes our cars. You will have to buy a new computer if you want to save your stock one. Or you can tune the one you have, just no option to switch back to stock if you mail in your stock computer. I think its around $400 for a new tuned computer.
As far as exhaust, the Magnaflow exhaust is the most expensive ($5-700) depending where you can get it and if its on sale. This is a bolt-on system.
You can custom make yours. I went custom as i dont have that kind of money to watch my new exhaust rust out. My upgrade is a 2.5" pipe from cat back with a perforated glasspack style resonator (i added this later cuz it was too raspy without it for me) and a free flow muffler. Total paid was $400 installed at a local shop after tax and a limited rust warranty. All stainless material.
