There are two Corsa systems for Tahoes. Neither of them are going to sound like a stock Denali system obviously. Since all you want is something that will sound similar to a stock Denali then I'd say get the Corsa Touring system. It has a much more steady, mellow tone as opposed to the Corsa Sport system, which is alot louder. Both will sound more aggresive than stock as they would be expected to

I've never heard of air intakes harming engines. As long as your mass airflow sensor stays clean, then it will always be able to get accurate readings and properly adjust air/fuel ratio ect.

The sound difference from the tahoe and denali is the 5.3L in the tahoe vs the 6.2L in the denali that is why the sound is different there is no different muffler.

Go Gibson if you want it a mild sound I have a Gibson Split Rear system and it is not loud at all.
