So, I've read about 50 posts on various exhaust setups and watched about all the videos I can find for 6.2L 2015+ GM truck exhausts.

My 16 Yukon Denali XL has the stock exhaust with the flapper bolt mod. I want to add a set of black tips similar to Corsa, but also want to get a better tone.

Options:

I found a deal on a corsa exhaust under $900 delivered plus $100 gift card. Install and hope it's not louder than I want.

Borla GM - maintains the flapper and may be too quiet, and extra $ for the tips.

Borla - no flapper but still have to buy the tips

Magnaflow 12909 muffler swap, but adding the dual side-exit tip means deleting the resonator as well. Will it drone or be too loud if i do both? Thinking about deleting the flapper too if i do a muffler swap.

I like the sound/tone of the magnaflow videos I've found, but afraid deleting both the flapper and the resonator will lead to issues.

I like the price on the corsa kit, but afraid it will be too loud for me (but I am running 33 MTs so noise isn't going to bother me too much).

I'm not really considering the Borlas right now even though I run some on my 72 K5 Blazer and live the sound/tone.

I just went with the GM BORLA on my RST and love it. Unless you are wanting to be that guy that wakes the neighbors it is plenty loud.

Definitely don't want ridiculously loud, just a touch more volume and maybe a touch deeper tone.
