Update - Anyone remove the resonator on a SLK55 AMG?
Original Post
Went to Fabspeed Motorsports yesterday and had my stock exhaust modified. I verified that there are no perforations, baffles or restrictions in the stock AMG mufflers. They are the equivalent of a straight pipe. The resonator is also a straight pipe but has perforations with packing to dampen the sound. They removed my stock AMG mufflers and resonator assembly as one unit so I can reinstall back to stock. They installed stock AMG mufflers (from eBay purchase) with a straight pipe in place of the resonator so this is effectively a straight pipe from the secondary cats back to the exhaust tips. I had the stock mufflers polished so they look great.
Exhaust sound is very subjective, so to some this may be too loud and to others not loud enough. For me, the sound is fantastic, much louder than stock but not too loud. The car finally has an aggressive sound to match the aggressive performance. It really sounds like a V8 now. The sound at idle is close to stock in volume but the frequency sounds much lower. Surprisingly there is no resonance inside of the cabin. The sound at WOT is pure music. I will post sound files if I can get the recording equipment out this weekend.
Jay at Fabspeed had the fabricator sketch the stock system so he can possibly duplicate this. Not sure if they are ready to do this but if they receive enough interest I would guess they might. You may want to contact Jay if interested.
Regards, Ed

I ordered new microphones today from SoundProfessionals. I should be able to get a better recording while driving as soon as they arrive. I’ll post as soon as possible. I will post the pictures at the same time as the recording!!
Here is the Stock SLK55 AMG stationary in the driveway:
