I have an EG with a b18c and a skunk2 megapower exhaust 2.5' with a high flow cat as well. Other upgrades: aem cai, skunk2 intake manifold.

Anyhow its too loud and annoying to me and others, I know skunk2 is known for being very loud, maybe the loudest, but I trying to figure out what my best option is. (without killing the power)
Options I'm considering:
1.replacing the entire skunk2 system with apexi ws2 600$
2. replacing the muffler with apexi ws2 universal muffler 270$
3. adding a vibrant ultra quiet resonator 100$ + labor
4. adding both a apexi world sport 2 muffler and vibrant resonator. 370+

Which do you think will work the best and bring down the noise level the most?
Another option that will kill 10+hp throughout the band would be a stock GSR exhaust.
