exhaust systems for 07 S550?
You can save some money and go find a good muffler shop.
-For more exhaust sound. Try muffler delete. cost is minimal. a lot of other benz model forum user have done it. Have the muffler shop remove the muffler to see how you like it. it will be louder
-For all out performance you need to run pipes from after the catalytic converter to rear bumper exit. I would run a X-pipe in the middle to help exhaust flow. Add silencers/mufflers to control sound level to your liking. Depending on what silencer and tip options you go with this can cost up to $1000
