ok i have a 05 cobalt 2.2. i put a aem air intake on it a a tsudo exhaust. love the sound and it gave me a lil more top end power but i seem to have lost the lower end. how do i increase that. im looking at putting the 2.4 intake manafold on it. does that mean i need to change my exhaust header to a 2.4 also or will the 2.2 work fine and ive also read that if i do that i lose bottom end to so like i asked what can i do and what should i do should i buy a computer or get it tuned i also see its cheapest to my the parts for the manifold at gmpartsdirect but i need a spacer cause i have a 05 where can i buy that spacer

To increase your low end, go back to stock. Putting the 2.4 intake manifold will cause you to lose more low end torque, but gain in the top end (3500rpms+)
But if you still want the 2.4 intake manifold look to create engineering depot, they sell a kit that I believe has everything needed for an 05. It was a direct fit on my 07 so I ordered mine through zzp
