Exhaust Mods For W211 E55?
Any tips would be appreciated!
I've seen people pull the guts out their muffler and this does provide a nice note but it's a pretty radical move. Once you see how tight that thing is packed you will understand why the E55 has a relatively quiet exhaust. I have an x-pipe and res delete and this provides a nice balance insofar as it roars when going WOT but without drawing attention when cruising normally.

Off topic but where did you get your lip from? I found one I liked today at a reasonable price ($275) but they wanted $650 to freight it to Australia so apparently I'm still looking... PM me if you like so this thread doesnt get hijacked.
Has anyone tried the cutout on their exhaust?
I did a little more research on res/cats/muffler deletes and there's plenty of good info throughout these forums. First if you do want more power that is only possible by getting rid of your cats. Renntech claims +10 HP and +15 LB-FT with their secondary Cats remove:

Many people don't like the sound of both the resonators and secondary cats being removed though so have a listen to a few cars on YouTube first to decide how you want to proceed. To me it produces a rawer and raspier sound.
Installing an X-Pipe is covered nicely in this post and includes answers to common questions: https://mbworld.org/forums/c-class-w...-answered.html
And finally you can purchase an X-Pipe here: http://www.magnaflow.com/02product/02xpipekits.asp

Thanks! I'm mainly doing this to bring the sound out more, but not to the point where it gets annoying. I can care less about the gains, but a little would be nice lol.
I've heard the #12229 and they sound great in the videos. Any feedback? What type of mufflers to the FTP performance exhaust use? They appear to be magnaflow as well.




Headers minus primary cats or muffler (C63, aftermarket(beware of drone), or removing the packing from the stock mufflers is the way to go. Combine them and get quiet cruising loud WOT
You still don't know that's what you want but trust me on this one- you want Eisenmann mufflers.
I got the Eisenmann Race mufflers- it's a freak'n machine gun, what a symphony!
