What downpipe do I need?
 

I have an 08 cobalt ss tc, and I was wondering if someone could send me the link to the exact zzp downpipe I would need to get? I want catless and I know the flange sizes but on their website they have a cobalt downpipe, and an ecotec turbo downpipe. I'm confused because I have a cobalt, but I have an ecotec engine. I'm sure this sounds stupid but if someone could help me out that would be sweet.
