Need help!

Can anyone suggest a "reversible" add-on or replacement exhaust system/pipes for a 2008 CLS 550?

I want the engine to sound like it has all the horsepower that it actually has (should have gone w/ the AMG)!

Already spoke to the MB service guys and they couldn't help me. A 3rd party performance shop recommended to just go to a straight pipe and changing or completey removing the silencers.

Any thoughts?

p.s. reversible since it's leased!
