is that the resonator? I was looking at the slk55 exhaust system, and there is an extra box b/w the cat and muffler, wut's the difference b/w that? and I see ppl cutting off that resonator b/w the cat and mufflers.Resonator (muffler) is located aft of the catalytic converters and X-pipe. It is visible on Ynot's photo to the right lower side of the photo.
As mentioned before de-cat will not pass emissions, not a good idea, there are options, you can get free flowing sports cats on ebay for $95 each (link on mbworld in the SLK55 section), go to a muffler shop and get it welded along with a new x-pipe and quad tip mufflers, it should sound very good, not sure how much power increase/decrease, should run you about $800 USD. I thought about it but decided to go with something proven. Good luck.uh hhuh! i see now! thankss
so would it be any diff. if i de-cat it? would it haf loss or gain anything?
