Itching to get my tune but wanting to improve my exhaust note along with an intake before doing so. It needs little something else over stock to tickle my ears.
From what I read, the factory cat back has little or no inefficiencies in it, so I planned to just follow the popular trend of LT's with factory cat back. If I do go this route, I'll go the econo-mode and get OBX or pacesetter... given I'm really just looking to pick a bit more growl and not as concerned with inching out every possible hp or lasting 10yrs.

Does anyone have other suggestions to consider that will give me a QUALITY growl... not loud or annoying.

Oh, if someone can give me the secrete to make it sound like my neighbors new z06 I'll give you a GOLD STAR!

electric cutout....be done with it. loud when you want it and quiet when you dont all with the flip of a switch in the cab. there are a few threads about this already and i post the same thing in every one since i am so happy with mine. DMH 3.5" electric cutout and a GOOD welder can do wonders. mine looks almost like it was from the factory

I have a resonated Aeroturbine muffler on my 6.2. I did leave my stock rezzy cause the wife doesn't like highway drone. What sucks is that aeroturbine went out of business but I know where there are some in stock still. We tried, flowmaster, magnaflow, cherrybomb, & borla. I thought the aero had the best exhaust note.

Here is the only sound clip I could find. This is not my truck, but I hope it helps.

Is this what they come with from factory, or are u just saying that corsa will give it the raspy pop like vets have? I personally dont think that sound note will go good with the looks of a truck, Almost make it seem like 2" dual straight pipe when coming from a truck

He's just saying that the Corsa will make it sound like a factory Z06; Z06s run GM muffs with a butterfly valve in them.

Thanks for the input guys! I may spend a little more time looking into those cutouts. I've found a few threads on them but can someone answer: ...at what location in the exhaust would the cutout be best located? between the Y and the muffler?

I also have to say that aero turbine muffler sounds pretty clean. congrats on that! Is that the AT3535 or the AT3535XL?

I had a Vortec glass pack style muffler installed in place of the factory and then removed the resonator. Eventually I am going to pick up a Corsa cat back once I get my LT's and all that but for now I like how it sounds and can't beat it for the price.

There are some other videos in my channel that you can hear the exhaust in as well
