I have a 2003 ecotec with CAI, Fuel/Air Ration Sensor Chip, Catalitic Converter, Catback, and headers are on their way to my house. When I install the headers I'm going to take my converter and muffler off and run a straight pipe. Now I don't know which mod should I get for Christmas; a throttle body to complete all my air flow mods or get new cams. Maybe get both for Christam if I rack in enough money? Which one first though?

Go Cams. A throttle Body might shift your powerband higher than you want upwards.

Yeah i regret buying the catilitic converter, it helped me some but it would help more if i didnt even have it in the first place; regret buying the muffler as well. And I got that chip as a gift, why take it off though?

It doesn't do anything but use more fuel. I wouldn't remove the muffler or cat.

that chip is garbage. it dont anything.
removing your cat and muffler is wont do anything either, unless you are pushing out high horsepower. and would probaly result in your exhaust in sounding like total crap

The TB or cams would be nice. My only concern with cams for the ecotec is it seems people were having issues with codes, not sure if that is fixed or not. Search around and do your research before doing cams
