Hello and thank you for bringing up this topic, I've had my fair and share with Kleemann and I can only tell you that I am really satisfied in having one of the professionals in the industry work on my car.
I have the full bolt ons which include Headers with downpipes, secondary race catalytics, Green filters, SuperSprint/Carlsson x pipe, Ecu upgrade derestricted for 98 octane and I must say the car is a real sleeper it really stacks up with the faster and more powerful cars due to its torque and availability at lower rpms. The car feels more powerful downlow due to the free flowing exhausts and ther larger diameter in comparison to the oem headers which are tight and small in diameter.
The car launches violently now and I've launched it from a stop and even with wheelspin the car catapults aggressively without having to burn too much rubber and staying in one position.
Here is my narrative from the upgrades,
--------------------------------------------------------------------------------
Today is a day I will truly remember for the rest of my life,
I am extremely moved with the joy that I received when I got my precious SLK 55 home. Let me first start of by telling you how powerful the car is at the moment, you've got to experience the torque curve to see how fast my baby monster catapults from the lower rpm's to its 6,700 rpm. The car is one ultimate sleeper if you are judging it by its looks, however open the tap and this thing will move like there is no tomorow, I was patiently waiting at the service counter in all silence reading the Mercedes Middle east magazine when I heard a thundering growl that is getting closer and closer. I said sounds familiar, like a mother recognizing her childs voice however it has matured and sounds even louder and deeper.
I told the service assistant I will be back shortly, I went out and saw my beautiful pride and joy parked outside glistering nicely showing of its nice metallic dark brown hue in Kuwait's hot daylight. I was lost, didnt know what to say and how to thank them for providing me with this terrific service; we then took the car for a drive and wow, the SLK has really gotten more powerful and I can assure you that I can feel the change in performance.
For any of you would like to do upgrades, Kleemann is a great company as they have called me a couple of times during this process directly from Denmark and I appreciate them for checking with their customers. I know its been a long long time since I've created this thread, but the end the wait is worth it as I am really torn up how to start and end this narrative. Its like waiting for your newly ordered SLK to arrive but in a shorter time line.
I am more than thankful for having the opportunity to have a nice car at this life time and I owe it all to hard work and determination in work. I think this might be my last modification as things are getting more expensive to upgrade it to the next level which are cams, supercharger and lsd.
Well, I always go with this saying " Be thankful for what you've got" and I am really blessed and very excited that I didnt get the CHECK ENGINE LIGHT after many attempts of having to be the Stig around the streets next to the dealership and at home.
I hope you've enjoyed my narrative as I've tried my best to write it in a short time because I know you guys are tempted to read it as soon as possible due to the long wait.
For those of you who are going to modify now or in the near future, I'd stick to professionals in the industry like Kleemann,renntech, carlsson, brabus and the other european tuners. What ever that they may be, you will be one satisfied customer at the end of the day.
Well, I've enjoyed keeping you up to date in the last few months and I really have to go to work right now.
The thread for my work,
