Changing your rear muffler from the stock twin outlet to a free flowing one will help BUT it will change how the car sounds. If you dont mind a little more noise and perhaps a little (only a little) drone then is fine.
Just be sure to get a price for fitting first. Sheesh. Exhaust shops in my town think it takes three plus hours to fit HM headers. True story. Takes me (with on arm and no hoist) 1.5 hours.
