Catback Exhaust Interchangeable Question?!?!

Hey. I have a 2010 cobalt 2lt. It's a 2.2. I found a catback exhaust on eBay that I really like but it says it's for a 05-07. I heard that as long as I don't have an SS, that it will still fit on my 2010. Does anybody know for a fact that this is possible? Thankyou

Just verify that you have a two bolt flange from the dp to the cat back system. If so you are good to go 05-10

The path for the catback is the same for na or ss. The only thing you have to worry about is the flange. Like I said, if you have a two bolt connecting the dp and the catback you are good to go.

I believe it's only a 2 bolt flange. The SS's have the 3 bolt ones If I'm not mistaken

Also, do you know the size of the piping for the exhaust, there are 2 exhausts I want to get but one has a 3" tip with 2" piping. The other is 4" tip with 2.5" piping. Not sure if that matters or not

2.5" is big but go that route, 2" piping is basically stock. My gmpp performance exhaust is a 4" tip and it doesn't look stupid if you're worrying about that

Yea I was worried a little lol. Even if it's a 2.5, the flange will still measure up to the stock flange?

Alright cool. Is The reason I should go for the 2.5 because if I went for the 2" (which you said is basically stock), then it seems like it obviously wouldn't have any true gains to it. But with the 2.5, it seems like there's more room for exhaust to be pushed out which improves efficiency. I'm guessing hah. I'm anal when I spend any kind of money on my car-_- sorry

basically buying the 2" exhaust would be like buying new rims for your car because the old ones are dirty. No improvement but it looks shiny
