The one thing that GM really could have done better on the Denalis/Escalade/LTZs is put a better looking exhaust tip/resonator on there! This thing has been an eye sore since day one and I have struggled to come up with a fix. I love the way the stock exhaust sounds, so I thought of getting Corsa or SLP resonator delete twin tip kits- but then I heard they can whistle with throttle. NO THANKS! So the day has come, I bought a Corsa Touring Hoping to get this and the other goodies that are piling up installed- once the Blazer is out of the garage that is!
