So i just signed up today because I bought an 07 Grand Prix a couple of years back and want to start adding some HP to beef it up a bit. The sites say that it comes with 200 HP stock but Im not a believer that I am actually getting that at the wheels. My first question is where should I start? So far I have come up with adding a cold air intake to it and then maybe a custom exhaust system. I have posted a link below to the air intake I have picked out. Im not sure about what exhaust system to go with because I have had some issues finding what will fit the base model Grand Prix. I am assuming that most parts that fit the GT will also fit the base model since there isnt much difference except for dealership 'interior packages'. Overall, Im trying to stay away from having to change out a lot of internals in the motor since it is rather expensive to do. Thoughts? Thanks in advance.
