Hey everybody people like me must show up all the time so if you could put up with my shit for just a minute and help me out that would be great. Now I do a lot with performance, I deal Diesel Performance, but cars is all new for me and I have never dealt with a supercharger before. I just got myself a 2006 2.0 Cobalt SS Supercharged. Now I have gotten myself a MagnaFlow exhaust system because they are a company that I deal a lot with and It was FREE. I would like to know what everybody thinks of that System. Good Bad Whats Better? Also I would like to push some more Ponies out of my car. 205 HP just will not cut it for me I deal with 500-600 HP Trucks all day and I like when I get laid in the back of the seat if you know what I mean. So what else can I really do to make this car Fast and when I pull up to a stoplight I want people to Know That’s My Car And That They Can't Touch It. People here seem to know what they are talking about and that’s the kind of people I would like to learn from. Thanks for the help and any advice that you can offer.;)

get a stage kit! if you don't care about the cars warrenty go with a intense stage 5! or if you do care go with stage 2

How many ponies are we talking about?

Sadly gas engines are not nearly as strong as diesel. You need to build up the engine, drivetrain and intake/exhaust if you want to add a LOT of power. Especially on a FWD. My brother added over 125HP on his truck with nothing more than a tune. For me to do that is going to involve an engine rebuild, transmission/driveshafts, new engine back exhaust system, and will total around ~40k when everything is done for a ~450HP car, if all goes well.

For a first step, if you want street legal, get a cold air intake, 3" exhaust system, and at the very least the GM Stage 2 supercharger. The should put you around 255HP or even 260HP or so. Dropping to a 2.8" pulley may get you to 275HP or even 280HP. After that, you are looking at serious dollars. The preceeding work should cost about $2300 or so.
