2014 CLS63-S
Exhaust Mods
Hello everyone, looking for your guys opinion on what I should do to the exhaust on 14 cls63 s.
Been considering the following:
Res Delete
Muffler Delete
If you have done either of them please let me know your opinon, if you have both done even better. Or even why I shouldn't do either would be appreciated.

Res Delete give a nice bump in sound, and turbo flutter, without being obnoxious. Just do the res delete with straight pipes and you are good. Muffler delete on top of that will be out of character for a benz. If you must do both, do a proper cat back with full 3" resonators and muffler. A custom shop in Toronto probably charge you are 1200 bucks to do it right. I use noyzboyz in scarborough. Talk to John.

deleting the mufflers is a really bad idea, Deistic told me you'd lose some torque and for sure lose the mag aggressive sound volume. it wouldn't have a Benz sound anymore, infant just like any other V8 turbo charge.. which sucks tbh. I had to buy stock mufflers which were hard to find and reinstall them.

On my 2012 E63 I had Catless downpipes, x pipe and it sounded unreal, but we couldn't stand the smell.
Now on the 2015 CLS we have only res delete, and straight pipes, and it sounds horrible. I hate it, and can't wait to change it. So I was thinking of removing the mufflers, and bridging the straight pipes into an X pipe.

I had a 2013 with catless downpipes and resonator delete with straight pipes. It sounded awesome and borderline out of context for a Benz at full throttle.
I have never heard a 5.5TT with no catbacks so I cannot comment about it.
I would first spend $250 to do resonator delete. If it's not loud enough, it is easy to take the mufflers out and run the car to see how it sounds.

I would be worried about it being too loud making any modifications. With the windows down, especially in S/S+ mode, the car has quite a bit of rumble and low-end burble. Reminds me of a truck engine sound actually lol

We just cut mine out, and I was looking through them, I saw no joins or interruptions. I saw two straight through channels.
