Muffler delete
Hello everyone, new to the Corevtte world and this forum. I have a 2010 Grand Sport automatic. The first mod I'm doing is a muffler delete. Shop I'm working with said this is quickest route to a better sound and they said the resonators keep the noise level down enough. If it turns out to be louder than I want I'm considering the SLP loudmouths. A tone run bing just resonators ? Opinions?

I bought an LS2 with a muffler works 5 dollar delete. The cats were still in place. I recently did long tubes, x pipe, no cats and NPP. With the NPP open the car is louder than factory manifolds with cats and muffler delete. You will have to make that decision once you have done the delete. The NNP gives you options.
