I just bought a 1997 S500 and am trying to find affordable aftermarket performance parts and am having very little luck. I love the car, but am looking for exhaust and hp gains. Any info will help.

 

welcome mark.

M119 is difficult engine to mess with, and as you can see... too crampy inside the engine compartment.

increasing the compression and replacing the piston to maximum oversize can increase power, but not much.
