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.
