A friend and I have upgraded the cars at Klemmann.

2014 SLK55 AMG R172 with P30. ( Speed limit 5 geare / 290 km/h )
Before upgrading: 543 Nm / 4765 Rpm and 426 HK / 6422 Rpm

My car 2013 SLK55 AMG R172 withoute P30.

Step 1:
Disassembled sec cat.
LSD diff, big difference from original .
Replacing the center resonator to an X-Pipe.
Electronic supplementary flap control from Chromtec.
559 Nm / 4471 Rpm and 404 hp / 5629 Rpm. (Runs at speed limit for 5 gears / 260 km / h)


Step 2: Same as step 1 with ECU upgrade from Kleemann.
593 Nm / 4298 and 442 hk / 5968 Rpm

Step 3: Same as step 1 and 2:
New Headers.
New sports cat.
632 Nm / 4239 Rpm and 478 Hk / 6091 Rpm

The car has become super fast and the sound is insane !!

Now you just need them to put a supercharger kit on! :D Turns the car in to a real beast. Smiles for miles! Nice upgrades, these things are addicting.

Have never tryed it with closed flaps, the sound is too great with flaps open! :)

An SLS owner tryed it and he said that the sound was very close the SLS when downshifting in M mode, but abit louder then the sls overall.

Thank you for shareing the pictures. Interested to see close up pictures of those headers since they fit to M273 and I have been thinking of C207 E500.
