There are 2 sets of resonators fitted on an SL55. I removed the front ones, and the sound is incredible. Deep throat bass and louder. It makes a real roar, and makes people turn heads. I can only recomend it.
Dont remove both sets, that will make the exhaust to noisy.
Provide some feedback, if you go for it.

well, i'm assuming the 2 resonators are the same lengths as i haven't looked under the car. the car is getting worked on so i can't check. any help.

It would be interesting to see if there is a difference is how the exhuast sounds depending on which set of resonators you remove?!
SLcharger, and JCortney:
Would you gents consider taking a sound clip of your cars?

I removed my Muffler / sound clip attched
I took of my muffler and had a glass pipe installed. Here are some pic. and a sound clip with the mufflers off.
Its sounds awesomely great. did not remove resonators because worried about MAF error.

SL charger thanks for all the great input, since you have removed the larger one, is the resonance mild. i know it's hard to say as you have a larger down pipe and headers, changing everything, but a guestimated answer. that is if you don't mind.

Resonance, hmmm. There is a resonance at idle that you can feel in your body, if you stay in a garage or building. It is not overwelmingly, but it is noticeable.
You are right, since i have fitted the Kleemann headers as well, and at the same time as the resonator was removed, i dont know how mutch the headers are changing or contributing to this sound.
The guy´s at Kleemann say´s that their headers tend to make the sound more deep. If you stay with stock headers, you might not get the full benefit, by removing the resonator, but my guess is that it will still be a different and more appeling sound.

Also, no sensors, no warning lights.
Hope this helps.

btw sl charger i am doing the kleeman upgrade k1 untill all fitment issues are resolved on the headers. and of corse i will be doing the LSD, as it can't hold down the power as is.

Have any of you guys noticed a drop in power or......maybe an increase? It may sound like it's faster but, it really may not be. Just wondering what the effects on performance are with less back pressure.

You will love the LSD. Mutch better handling.

I honestly don't feel any difference either way.

the word is the fitment of the headers is shaky, but then most headers are.

The resonators are placed a little after the headers. You can remove these and run straight, x, or y pipe etc.
The cats (catalytic converters) are placed before the mufflers. Don't remove these unless you're replacing them with an aftermarket setup. I believe this is where the O2 is too.
The mufflers of course are at the very end. Don't remove these either unless you are replacing them.
Hope that clears it up a bit.

well i got the car back from Lucent Motors (the bomb). the Kleeman K1 is very torquey especially down low. a little twitchy but nice, unfortunately they did not have the LSD yet so i'm still waiting as the car absolutly needs it and i don't know why it doesn't have it from the get go. and today i removed the resonator, which by the way is right before the muffler, not after the headers or any of the photo's shown above those photos are the cats. there is only one resonator on the car, besides the muffler itself. the sound is dramatically louder/ throatier. it really wakes the car up, but not sure if it suits the car as it is a cruiser. so if any of you are planing on doing it, it is significantly louder, but not that much that it creates harsh cabin drone/resonance.
so the K1 is a thumbs up
LSD is a must
removing the resonator is loud

The complexity off language sometimes leeds to missunderstandings. When this tread was started i got the impression that you people call a Cat , a resonator, and wise versa.
Anyway, since this is now cleared, i moved the front cat´s. The rest of the story is still the same.
