The title says it all. I really want to make this car louder but I do not want to void my unlimited mile warranty. Any suggestions?

Add a cat back exhaust

Renntech mufflers may be all you need

very little if anything would happen to your car that would not be subsequently covered by warranty

BUT THIS IS DEALER DEPENDENT

the vague concept of “voiding a warranty” is much more of a conversation than just .. limiting mods to stay out of a danger window. You should ask your dealer if they would continue to honor the warranty if ANY cosmetic or performance mods are done. You can also go to renntech website and see which Benz dealers are renntech friendly

That's not a worry:

https://www.edmunds.com/auto-warrant...-warranty.html

"The saving grace for consumers is the Magnuson-Moss Warranty Act of 1975. The act states that a dealer must prove that aftermarket equipment caused the need for repairs before it can deny warranty coverage."

people bring up the MM act all the time ... in real time dealers can still do what they want and it’s your burden to fight them and go through the process

Those are about tunes. In the context of this thread, there is no chance a dealer is going to void an engine/powertrain/larger warranty because somebody replaced a muffler or resonators.

Adding cat back will void warranty only on cat back exhaust.
adding down pipes will void warranty on engine and everything what controlled by ecu.
buying brabus exhaust from dealer won’t void warranty and fitted by them
that what my dealer said long time ago.
