I have a 2009 Cobalt with the 2.2 Ecotec normal asperated and automatic trans. Does any one have any advice as far as headers, cold air intake, and cat back systems?

Thanks for all your help
Dimitri

 

yeah uh dont put a header on it.....that car is so high tech that if you switch the exahust up on it, will for sure throw a code.......cold air and cat back system is fine.....most newer cars have tubular manifolds on them anyway which are alomst the same as a header....
