I had my resonator deleted and its real easy. price may vary on where you live but I got mine done for $80. There are some guys who paid less than me and some who paid more. Any muffler shop like meineke should be able to do it. All they do is cut out the resonator and weld a straight pipe in place of it. Ask them what kind of piping they will use in place of it? Make sure it will be a non rust pipe. But yea, its real easy and doesn't take long at all. It may not sound so awesome at first b/c your ECU needs to adapt to it and make its changes. Also it doesn't sound like much at a cold start but once it warms up, it sounds real good. I get compliments all the time. To me it sounds the way a Mercedes SHOULD sound. Not obnoxious, but not silent. It is definitely more throaty as well. Good luck with it. Here is what the resonator looks like...

Unless you want a real aggressive and obnoxiously loud sound, you will love it. Just give it some time to warm up and adapt to your car. Ive had people on motorcycles pull over and tell me it sounds awesome.

Ive removed the resonator on my SLK55 via the SuperSprint/Carlsson X pipe and Installed Kleemann Sport primary 200 cell 3" cats, the sound is intoxicating.

I would suggest you to get your Ecu Remapped, Drop in filters with the Resonator removed for a 13-18hp increase. For the Airfilters stick with Green filters.

Getting your resonators chopped of and replaced should cost you no more than 50$...

It depends on where you live!!! I got mine done for $80. It also depends on what kind of piping they use in replacement of your resonator. I got mine done at meineke. Some will do it, some will not mess wit it. Any custom exhaust shop will do it for you, just call before you go in case they dont want to do it.

Good advice.

Called 6 places in SoCal, 4 wouldn't do it. One claimed it was illegal because he said you cant modify the exhaust of an obd2 car. the others just said they wont do it because of liability blah.

But i found a few to do it for 50-100 bucks. Unfortunately, as soon as they see the car, they want to charge more. I'd go in telling the store that you've gotten quotes from other places for 50 bucks and see what they do.

I'm getting it done monday, i'll post a video clip afterwards.


Any other cheap mods I can do? I'm so bored with this car already.

Hey guess what, there are no resonators in an SL500

I ended up straightpiping the 2ndary cats and...

Damn, I gotta say. Best money i've spent on the car so far. It sounds much more throaty and much less muffled then before. The highs are crispy and the meds have been amped up a little bit. The sound really comes alive at around 3-5k rpm.

Performance wise I do think i'm seeing an improvement. My tires spin a lot easier now and it feels like i've got more torque. I was cruising home last night with music cranked up high so I couldnt hear the engine, it still felt more responsive. After looking at the 2ndary cats it does look like the backpressure was too high.

Bottom line: Driving it is more fun now

Here's a pic...forgot to take one of the after but it's not hard to imagine what it looks like

Videos to come later.

I'd like to hear a sound clip before deciding either way.

So straightpipe the secondary cats and not the primary, correct?
Don't the cats serve some useful purpose?

Yeah they reduce emissions so you will fail your emissions test if you have to go for one. Its about 100 bucks to cut them out so not exactly wallet busting... definitely worth it imo.

Here is a quick vid my buddy Roupin made...i'll try and get some more. Keep in mind, the real thing sounds a hell of a lot better, wasn't really flooring it in this video either.

You could even get a muffler shop to remove the Mufflers... and leave the emissions unchanged...


it actually makes the car sound like an SL65... really throaty in WOT, but otherwise pretty quiet.

those cats really quiet down the car..

Might be a dumb question, but if we need to get emissions done, will they be able (I assume) to weld the cats back in?

I've heard that would sound way too loud, thats why I opted to remove the secondary cats. I really doubt it would be quiet even at idle, mufflers on the SL500 do quite a bit of muffling considering there are no resonators...

That said, i'd still love to hear one

Mj, yeah, they can be welded back on easy.

I upgraded to the 55 mufflers, and that changed the sound ALOT!

I still have the cats in, but the car sounds mean. People keep asking
about my car now, because it sounds dangerous.

I was about to do that, do you have any audio/video clips? I'd love to hear it!

I dont, but everyone who has heard it says it is much deeper
than my friends CLK 55 (MY '05). Supposedly friends can tell
when I punch it to pass them in traffic, because they hear it
get more aggressive.
