Does anyone have a dyno of a stock C55 after a resonator delete?
Resonator deletes usually reduces backpressure but I think that only works in favor of a forced induced motor.

Any before/after dynos?



When you say 50hp increase do you mean along with ECU and airbox right?
message member named "MBH motorsports" (his actual name is Mike and used to have a highly modified supercharged C55) and ask him for specs/pricing. tell him i sent you

Stock C55 with 20% drivetrain loss is 285 rwhp and 300 rwtp
So if I am getting this right, with your resonator delete and K&N filter you made 305 rwhp and 316 rwtq.
After adding the ECU you made an additional 15 rwhp and 30 rwtq increase without headers? So that would make flywheel horsepower about 420 and torque at 440?

What dyno did you run on?

not sure what dyno it was, check my sig. for the dyno runs. i did the same dyno on my E63. it was at dittos motors in daly city, CA.
And the part that still has me puzzled is you had great gains without headers

IMHO, the reason no full exhausts were developed was becaut the C55 has a production of only 1750 vehicles to the North American market. Assuming that what I've read about the US getting 40% of AMG production, that would mean a whopping 4375 worldwide. Given that most owners will not mod their cars it would be stupid for a company to invest much in product development. The mods that are available were developed for the engine, not the chassis.
My custom exhaust was a little over $900 iirc.

The C was always the ******* child anyway. It never took off until the W204. That's why the CLK got all the cool factory options that the C could have easily had since it's the same car with two more doors. Plus, all the companies making performance parts for Benz focused on the E since it left the factory with a supercharger so it was easier to make faster.


4.600 C55´s were made in total between late 04 and early 07.
1.750 were shipped to North America, all sedans.
Maybe 1.750 were wagons...
I believe that there is not much to gain in a Horse power increase with a Res delete. Just maybe a noise incrase. The real Hing pin is the exhaust manifolds . Stock manifold outlet is a little over 1.5 ". The Klee Headers are 2.5 ". Somewhere Here are some answers ? https://mbworld.org/forums/clk55-amg...er-review.html. I'll find the dyno sheets & Pic

The resonator takes away some drone and is a big straight

Funny enough I hear zero drone with the resonator delete.
