Mercedes SLK55 2009 Exhaust Mods

Some like it hot! Whether you noticed or not, the tunes trumpeting out of the SLK55 exhaust are more robust during cold starts but soon diminish as the engine warms. One owner of a 2009 SLK55 likes the cold start sound and he would like to keep it full-time. Any reader suggestions?

Here’s Bruce’s question – leave a comment if you have an answer for him:

I want to get more sweet V8 sound from my 2009 SLK55. I don’t care about the stereo. I want the exhaust to sound way better than it does. What is the best, least expensive way to do that? Is there a solenoid that closes down the sound, soon after a cold start. Because the cold start sound is great. It just doesn’t last long enough. Is there a “flapper mod” that would give the car more sound, or something else? What about an X-pipe to replace the resonator? Thanks for your help. My dealer has no suggestions…

Thanks, Bruce

Mercedes-Benz SL55 AMG Battery Drain

Has anyone else encountered a problem with their battery losing a charge when the car is sitting? Richard asks:

A problem has plagued my SL55 AMG for the last 2 years. I have since brought the MB AMG to service twice for the same problem. This last time the service mechanic replaced my second battery found in the trunk and gave me a battery conditioner that needs to be connected to the battery when the MB AMG is sitting. The manager notified me there is a drain on the battery that they cannot find. Is this a problem all ’03 SL55 AMG’s have and if not does anyone have an idea why there would be a constant drain on the second battery, and is there a fix? – Richard

Leave your comments and we’ll see if we can help him out – thanks!
