i've been surfing the web and found some hardcore info for possible stage 3 parts. can anybody confirm this information. the parts and numbers are:

17802111 exhaust $489
12499351 exhaust straight tips $65
19131972 honed exhaust manifold $335

i've seen that it will make the cobalt ss s/c produce over 300hp with the stage 2 kit. the info says 65 additional hp. with toolmakers dyno of 250 plus 65 that makes it 315hp!

if this info is accurate does anybody know of the release dates. i checked gm performance parts website, but no info was available, no surprise since i checked for stage 2 by part number and there was also no info available.

please help!

All them parts are out and have been out for along time. They are not stage 3 there just some parts you can get.

Later

thanks. i was wondering if/when somebody was going to get back to me on this.
