get rid of the jbp header, and get a good header downpipe combo. also look into a catback exhaust, and a dual pass. with those additions, along with the mods you have listed, you could be looking at 255-265whp.

the header is junk, trust me. it doesnt flow well with all of those crazy ass bends. you would feel a much better gain from a good header downpipe combo from clear image, zzp, or vibrant for example.

a high flow 2.5" system is more than enough for a supercharged cobalt. 3" is overkill until you start putting down 300+ whp.

header gains before the s/c were great but ill keep it in mind in the future. something about a $600 paper weight doesnt sound good to me.
