Magnaflow is making exhaust for diesel WK

I was looking online for options on exhaust systems, I came across that Magnaflow is making a exhaust system, here is the info; 5 x 8 x 18in. Muffler; 3.0in. Tubing; 3.5in. Polished Stainless Tip; SINGLE REAR SIDE EXIT PASSENGER SIDE Part 16812. I know the MBRP doesn't have a muffler but the Magnaflow will. It seems that would virtually be the same setup as stock?

Re: Magnaflow is making exhaust for diesel WK

I wouldn't waste my money on an aftermarket exhaust system for the wk diesel. The stock system is 2.75" with a flow through resonator. You won't experience any gain with the dpf filter in place. Even with the dpf removed the stock sytem flows more than enough for the stock turbo. I have no dpf filter with no resonator and the exhaust note is barely louder than stock. I would get a good tune before any else.

Thanks for the input, yeah, I'm looking at green diesel engineering for the tune.

Re: Magnaflow is making exhaust for diesel WK

I have the Custom Spooling Tune with EGR and DPF delete. I think its the best and the peace of mind with those two systems offline. The power is awesome and super quick.
I have heard good things about GDE.

Re: Magnaflow is making exhaust for diesel WK

If the exhaust is sufficient then how about just fitting a new set of headers to replace the cast iron exhaust manifold? With that said, does anyone know who makes any?

The exhaust manifolds on the OM642 are tubular 409 stainless steel. I will call it the "merge collector" on the exhaust pre-turbo is the only cast iron in the exhaust manifolds. I don't know of anyone making headers for this engine. However, I believe this engine with the stock turbo will not flow enough air to need headers. I don't have any pictures of the stock manifolds with me, but if you google pictures of the engine you can get some decent pic of the manifolds.

I just got a tune for my diesel, what a wake up call! no header on my old 4.o or k and n filter cone ever did this! I actually can burn rubber now if I need to desire off the line with my 32's, Weird.

Seeing as you are close to me, where did you get the tune done and can I ask the damage to get it done as well please. Thanks
