Worked for awhile on this latest setup. No more switchable exhaust. Long Stainless Works mufflers replace the factory rear mufflers. Gain some power from the more efficient setup, gain some GREAT V12 M120 exhaust tone, but still get to be factory quiet when you want. Plus the AMG-style tips out the back look really mean. Stay tuned for more S600 content and soon Supra content too.
