If you're chasing that classic Camaro growl, I’d suggest going for some nice headers and a good muffler. That combo really brings out that deep, aggressive sound you want. For hybrid swaps, sporty coupes tend to have a better exhaust note, so they might be worth checking out. I’ve tinkered with a few setups, and I agree, the LMP1 cars can sound pretty tinny; it’s not for everyone.
