Aftermarket m271 Catalytic Converters
Are there any on the market? Magnaflow, borla. . . whatever? I want to replace my junk Kleemann high flow on my Kleemann headers but I can't seem to find a suitable replacement. Anyone please chime in!

Out Of Control!!
Magnaflow doesn't list any on its site. And Borla doesn't even list MB applications.
So unless you go with a universal, you may be stuck with what you got. What's wrong with the Kleemann? I'm sure it wasn't cheap.

The insulation in the cat is all effed up so its pretty much pointless. I may as well just take that out and straight pipe it.

If the cat is breaking down then get rid of it immediately. The design of the M271 with the cat so close to the engine it is very likely to suck broken material back in if the cat is breaking up (hit it, if it rattles its time to go).
Nissan Sentras were notorious for this, grenading engines.
Cannot run without a cat on the M271. Jose aka Mig888 tried, couldn't ever get it right even with an O2 sensor spacer and sim.

You could weld the stock cat into the Kleemann header.
