Everybody's a comedian!

Try Catco. The Bosal system is cat back, meaning they are starting at the outlet of the cat - not what you're after.

M-B does NOT manufacture their own cats so you'll need to find their source so you can buy it before they put it in a tri-star box and triple the price. I'll send off a note to my sister-in-law as her knowledge is current and mine's WAY dated. She's likely to know the maker that Benz uses.

Your exhaust shop probably has access to a generic aftermarket cat and they'll save you a pile of money.

A number of ways to skin this cat. (sorry, I HAD to do it)
