To answer your exhaust ?, yeah I did the u-bend delete, took the cat completely out (but its illegal in a lot of states) a high flow cat would be good, bigger piping from the cat-back and dual magnaflow mufflers. Thats about all you can do as far as exhaust goes without doing headers. I have headers waiting to be put on but I need to get an upgraded tranny to be able to run the headers. The stock tranny isnt made to handle that much horsepower! So im having a tranny built for my car right now to handle the horsepower and not have problems. I hope this helped you out. If you have any other ?'s feel free to let me know! Have a Merry Christmas and Happy New Year man!

Sorry it took me so long to get back to you I have been really busy lately, but on behalf of your throttle body questions. The throttle body is the part of the engine that lets air in. It is composed of 2 flaps (often called "butterflies"), which open and close accordingly with how far the gas pedal is pressed. A larger throttle body will allow more air into the engine, thereby improving the performance - both throttle response and horsepower. This upgrade should only be done after you've upgraded the exhaust system. The Grand Prix's stock exhaust is so restrictive that the increased airflow from a larger throttle body will make the engine run worse when compared with the stock one.If you increase the size of your throttle body it allows more air coming in, which allows more fuel to pump, which increases power. And for the throttle body spacer it gives a little more time for the turbulence to clear out of the intake air charge, in doing so the engine draws more air and mid range power is better. I hope this answered your ? if not let me know and I can try and explain better. Good luck and your car is really coming along nicely!
