Hello to all SL drivers, I want to hear my SL600 a little bit more and a little nicer. Does anyone have experience with another exhaust system? There are several suppliers, but no one has a sound file to listen to. I want to listen to deeper/bassier, but not loud – just a little more presence. What is the quality and fit accuracy of the alternative systems? (I don’t want the body to be worked around.) uspuff systems that can be turned louder and quieter at the push of a button. Is there something similar for the R230? Last question: Are there any problems with the DC warranty if you change something on the exhaust? Thanks in advance.
