2006 cobalt ss/sc : current mods are srs catback exhaust and k&n typhoon intake

suggestions on injectors and lowering kit and also stage 2 clutch kit??

 

search the forums. These topics have been covered multiple times.

 

You don't need injectors till you down size your pulley, and you can either buy some coil overs or lowering spring but that depends on your budget and how low you wanna go. And clutch wise, I'd say your stock should be fine unless it's already slipping, or you plan on buying a stage kit for it anytime soon, then I would personally recommend the GM upgraded clutch (zzp sells it pretty cheap) since it'll hold all the power you want unless you want to turbo swap or put a tvs on it.

And if you want to know more the search button is fairly useful once you figure out to use it properly. lol.

 

googling with site:cobaltss.net is way better than the search function here, hell the stickys in this section cover most of those questions

 

Google is way easier, and the top results are almost always from here. And there's a sticky for a guide to how to mod these that is Very Very useful. Use that stick OP.
