i have a 2006 chevy cobalt ss sc and looking on getting the ZZP stage 3 kit. only thing that concerns me is if i anyone can let me know if i need and additional parts? plus, i already have the SLP loud mouth exhaust (which is an AWESOME exhaust!!) on my car but other than that its completely stock. any help on what to get exactly so my car can push up to 270+ ?

If you want to run it consistently and be safe you need dual pass. Maybe look into headers and a down pipe if your exhaust isn't that far back.

 

Turbo swap, your going to more then stage 3 to get 275+
