The Truth

I am in the market for a 16 - 18 s63 coming from a 11 e550 with a res delete/x pipe and a muffler delete/j pipe which is why I am asking. Did the sound change significantly after the tune and do you have a video of the pre tune res delete? Thanks again for the replies!

My current setup

No, I don’t have any videos prior. If you search YouTube for stock exhaust sound for the S63, then it’ll sound identical. The tune and resonator delete is about 30% noticeable compared to stock. The burble/pops is definitely louder for sure! I wish I could somehow get a good sound clip of the tune/exhaust when the car is on the highway. It’s day and night compared to any stock s63.

The Truth

Makes sense! Sounds like a res delete plus the Renntech EVM should give it a nice sound to start with.

I have never had any check engine light issues with any of the modifications.

Just posted my video on YouTube (link below). 2015 S63 with resonator delete and MBH downpipes. No revs. Just a cold start. Rev clip to come (once I’m not near my neighbors, hahaha).

The Truth

Not to keep an old thread going, but would the consensus be straight piping the resonators instead of the xpipe option for sound specifically?

i am extending the thread only because of curiosity. 2014 s63, downpipes no cat and no resonator... stage 1 w/ burble. Nice crackles above 2k rpm and if i downshift at 70mph in 5th gear to 4th gear.. maybe 2-3 seconds of BIG crackles... overall it is nice but not ideal.

i may put the resonator back and see how it sounds w/ the burble... I want a more meater and heavier sound. The pops are cool but eh.... it sounds much more heavy with out it.

personally I think downpipes w/ resonator probably sounds the most heavy for m157... the burble is nice but can be too much for an s class

The pop is a show stopper but I don’t see myself revving a car like that…

The Truth

I also read the x pipe gives sound on idle, which original model of s63 2014-2017 are missing so there is less sound on idle neither low RPM, but newer models have sport+ mode, which also comes with xpipe. Not sure how all this lines up.
