Can anybody tell me which engine is in my 2011 CTS-V coupe? It's all stock.

Also, Anybody have advice on a product to get rid of the carbon burns in my exhaust pipes? I polish them, but the hard-core black stuff does not come out.

Is this a serious question?

haha, yeah! I like to keep my car pristine.
I get the carbon in the exhaust tip question, but it was directed to the question of what engine your car has.....how do you not know?

To clean the inside of the tips, you can try Mother' polishing ball or cone on a drill with some polishing compound. Maintain weekly with NEVR-DULL metal polish.

If he doesn't know it's an LSA, what are the chances he's going to find the VIN? :LOL:

On stainless you can use almost any paste polish, a buffing ball and a cordless drill.

For really caked on stuff, you'll want a lower grit and then jump up to finer grit for a proper polish - much like paint repair.

Then convert to ethanol and they will stay super clean (true story).

But yea.... dude. Which engine?

What are the last 8 of your VIN #? Do you have an automatic or manual transmission? Does it have a sunroof?

Elbow grease.
B0105124, auto, with sunroof.

Thanks. I don't know how to answer the engine question other than that I have gotten two answers, LS1 and LSA. I'm not a gear head, just a lover of this car.

Well, what can I say? As I said, mundane question. Seriously, sorry to bother you.

Stick around Mr. Finley, you can learn a lot here as long as you don't have a thin skin.

Take me for example, I knew nothing when I joined (but I knew it had an LSA😆). Fast forward a few years and I had the confidence to swap out my cam and valvetrain. Good people here!

Yeah, all good, no worries. I can see the level of knowledge here. Asking about the engine is like asking a physicist what an atom is. But I had to ask.

I didn't know they offered the flux capacitor in the 2011. I guess someone could have ordered it special.
