So I have a 13 Camaro 3.6L, was hoping to install exhaust headers right away since it's smog exempt for a while. (live in california)
but unfortunately, i can only find exhaust headers for 2010-2011, and so I took a more detailed look under my hood to figure out the difference and I don't even have an exhaust manifold. Just a down pipe, I guess the heads are different on my model.

The car sounds like a moped with stock exhaust and huge mufflers, wondering if anyone here installed nice exhaust on their 12 or 13 v6s that can recommend anything. I don't want it too loud, but I want to be heard. I've seen the magnaflows for my car and they're supposed to increase HP and torque but they look terrible. Any recommendations?

Also, I'm hoping someone knows about the new XTS 2014 twin turbo. It's a 3.6L, I'm wondering if the stock twin turbos would fit on a 3.6L camaro. I've got a bad feeling they only fit the 2010 and 2011 models because of the manifold and head change, but maybe they only fit the 2013 and 2012. Any info would help, I can't get much info on the 2014s yet. Thanks
