Aftermarket Magnaflow Catalytic converter PN 23836 for 560 and 420 SEL Mercedes Benz.


Was checking out some exhaust parts the other day when I noticed a new aftermarket catalytic converter setup for the 420 and 560's!

I have put a great deal of MagnaFlow converters on many different cars and trucks, in most all cases the fit and finish was really good.

It's Magnaflow part # 23836

It's a whopping $650, which seems to be the going rate for everyone online. Personally it seems like a price fixing, because honestly there is no way they put as much precious metals in these aftermarket converters as Mercedes did back in the 80's and 90's. Still, the original ones can get pretty nasty after a few hundred thousand miles and for anyone looking for a lower cost alternative for a daily driver this could be it.

Anyone given this setup a try?

Hello SELLC,

1. What's the small resonator looking object on the engine pipe ?...Is that a flexi-pipe ?...

2. Surely most folks would have woken-up by now & fitted a European manifold on the drivers side & found that missing 20-30-hp by having a "true" full-length twin-system ?...Or are the authorities still so tough on these things ?

3. It may be price fixing, but that $650:00 is a heck-of-a-lot cheaper than anything you'll find here in Oz, if only because we got the full twin-system like Europe, so you'll need to replace 2 x Cats LOL !

Cheers,

Rastus

The small resonator looking thing is the pre-cat.

I have been mulling a euro log style manifold setup, but you need both sides as the American manifold on the right side has provisions for the inlet from the crossover pipe. I was just more or less looking around at exhaust systems for the 560 when I come across this converter setup. They do help keep the exhaust quiet but at the expense of a restriction of the exhaust gases.

Still, even better than the euro log's would be the Tri-Y manifolds,

That's one mean exhaust setup with the Tri-Y's, just curious about the heat in that area and how well the manifold seal. I bet they seal well given the fact they are cast iron.

Here's a poor picture of a picture that has a 450 M117 with the Euro-logs mentioned by SELLC. Though they're not extractors or headers, they don't just feed the spent gas into a common large log either, so some care & thought has been given here at least !

Cheers,
