C55 Kleemann headers
with the downpipes it will remove the primary cats as well, if the smell is too bad, or it is too loud in the cabin I will had some high flow (probably 300cell) cats in there somewhere

if we can ever do anything for you let us know


Has anyone else had them ceramic coated to reduce underhood temps?
Do you happened to have pictures of your car from underneath? And did you use your stock mufflers or aftermarket?


with (snake-)headers before primary cats, and a different software. The cars
had more, like 19 inch wheels and CLK-front etc.
They claimed 400 hp for that version which is a gain of 33 hp.
Kleemann headers deletes the restrictive primaries and in combination with
their software the gains would be in the 43-48 hp range.
